The Man Who Invented the Computer: The Biography of John Atanasoff, Digital Pioneer by Jane Smiley (PDF)

Description

From one of our most acclaimed novelists, a David-and-Goliath biography for the digital age.One night in the late 1930s, in a bar on the Illinois–Iowa border, John Vincent Atanasoff, a professor of physics at Iowa State University, after a frustrating day performing tedious mathematical calculations in his lab, hit on the idea that the binary number system and electronic switches, com­bined with an array of capacitors on a moving drum to serve as memory, could yield a computing machine that would make his life and the lives of other similarly burdened scientists easier. Then he went back and built the machine. It worked. The whole world changed. Why don’t we know the name of John Atanasoff as well as we know those of Alan Turing and John von Neumann? Because he never patented the device, and because the developers of the far-better-known ENIAC almost certainly stole critical ideas from him. But in 1973 a court declared that the patent on that Sperry Rand device was invalid, opening the intellectual property gates to the computer revolution. Jane Smiley tells the quintessentially American story of the child of immigrants John Atanasoff with technical clarity and narrative drive, making the race to develop digital computing as gripping as a real-life techno-thriller.

Editorial Reviews: From Publishers Weekly Novelist Smiley explores the story of the now mostly forgotten Atanasoff, a brilliant and engaged physicist and engineer who first dreamed of and built a computational machine that was the prototype for the computer. With her dazzling storytelling, Smiley narrates the tale of a driven young Iowa State University physics professor searching for a way to improve the speed and accuracy of mathematical calculations. In 1936, Atanasoff and his colleague, A.E. Brandt, modified an IBM tabulator–which used punched cards to add or subtract values represented by the holes in the cards–to get it to perform in a better, faster, and more accurate way. One December evening in 1937, Atanasoff, still struggling to hit upon a formula that would allow a machine to replicate the human brain, drove from Ames, Iowa, to Rock Island, Ill., where, over a bourbon and soda in a roadside tavern, he sketched his ideas for a machine that would become the computer. As with many scientific discoveries or inventions, however, the original genius behind the innovation is often obscured by later, more aggressive, and savvy scientists who covet the honor for themselves. Smiley weaves the stories of other claimants to the computer throne (Turing and von Neumann, among others) into Atanasoff’s narrative, throwing into relief his own achievements. (Oct.)

From Booklist Several popular works have dealt with the question of who invented the computer, and novelist Smiley has obviously read and deeply pondered them all. She emerges from her immersion in binary arithmetic, vacuum tubes, and eccentric geniuses with a scintillating narrative synthesis that agrees with the prevailing technical opinion (Who Invented the Computer? by Alice Burks, 2003) that John Atanasoff, a mechanical fiddler extraordinaire, had the first computer functioning by 1941. But off the beaten path in Ames, Iowa, it attracted little notice after its builder diverted into war work, as did another physicist who had seen Atanasoff’s machine: John Mauchly, whose idea-sprouting indiscipline Smiley draws as vividly as she does Atanasoff’s cantankerous technical tenacity. Mauchly was central to the construction of ENIAC, once considered the first computer. Did he filch Atanasoff’s ideas, asked litigation in the 1970s? Before arriving at the courthouse, Smiley integrates into the story profiles of the computer theorists and builders of the 1940s, including Alan Turing, John von Neumann, and Konrad Zuse. Told with self-propelling fluidity, Smiley’s fine account will certainly draw more than the technophile base due to her literary cachet. HIGH-DEMAND BACKSTORY: This biography written by acclaimed novelist Jane Smiley is the first entry in Doubleday’s Great Innovators series. –Gilbert Taylor Review PRAISE FOR THE MAN WHO INVENTED THE COMPUTER:”Engrossing. Smiley takes science history and injects it with a touch of noir and an exciting clash of vanities.”–Kirkus Reviews“Novelist Jane Smiley shines her talent on the underappreciated career of John Atansanoff, the man recognized as creating the first computer… . It’s a rare treat to read a book about digital science in the language of an acclaimed prose stylist.”—Bloomberg Businessweek “[Jane Smiley] follows the John McPhee-perfected recipe for historical journalism nicely and with élan: take an abstruse subject, research it deeply, then humanize it tenderly, adding off-kilter insights and sharp portraits of the curious folks involved…. Smiley blends all these convergent and parallel narratives into a superb whole, as fetching and gripping as any novel. She displays an unwavering, cogent grasp of all the technical details, a keen eye for historical forces, and much psychological insight; her prose is a model of smooth transparency. Anyone who wants to understand the roots of our twenty-first century digital culture needs to read this book.”—Paul Di Filippo, Barnes & Noble Review About the Author JANE SMILEY is the author of eleven novels, including the Pulitzer Prize–winning A Thousand Acres, and three works of nonfiction. She was inducted into the American Academy of Arts and Letters in 2001. Smiley lives in Northern California. Excerpt. © Reprinted by permission. All rights reserved. Chapter OneJohn Vincent Atanasoff’s father, Ivan, was born in 1876, in the midst of a period of climaxing political unrest. His parents were landed peasants in the Bulgarian village of Boyadzhik (about eighty miles from the Black Sea and perhaps halfway between Istanbul and Sofia). The Ottoman Empire was breaking up–Serbia had won independence in 1830 and Greece in 1832. Revolutionary agitation in Bulgaria, which intensified in the 1870s, culminated in the April Uprising of 1876, in which bands of Christian resistance fighters attacked Ottoman government offices and police enclaves. The attacks were followed by a campaign of reprisal on the part of the Ottoman government. Ivan’s father, Atanas, and his mother, Yana, were forced to flee their village, Atanas carrying the baby Ivan in his arms. In the course of the melee, Yana was knocked unconscious and Atanas was shot in the back. The bullet killed Atanas and creased the baby’s scalp as it exited through his father’s chest, but Ivan and Yana survived (though American translator Eugene Schuyler estimated from his own observations at the time that fifteen thousand Bulgarians were killed, and five monasteries and fifty-eight villages–including Boyadzhik–were destroyed in these attacks). The revolution was put down for the time being and the Ottoman response was widely publicized and deplored, and then in mid-1877, Russia attacked the Ottoman Empire in the Balkans with the express purpose of liberating the Balkan Christian states and regaining access to the Black Sea that Russia had lost in the Crimean War. The conflict was short–the autonomy of Bulgaria was recognized in the Treaty of San Stefano, signed on March 3, 1878. Among the Russian cheerleaders for the war were Ivan Turgenev, who thought Bulgaria should be liberated, and Fyodor Dostoyevsky, who hoped to unite all Eastern Orthodox churches under the Russian church.Yana subsequently married a local cattle breeder who could afford to educate little Ivan, while her brother made contact with American missionaries, who helped him get to America. When this uncle returned on a visit to Bulgaria in the late 1880s, young Ivan, now thirteen, decided to go back to America with him. Yana financed the trip by selling a piece of land that Atanas had left her.At Ellis Island, Ivan Atanasov’s name was changed to John Atanasoff. Although he had a bit of money, it was only enough to rent a room in New York City so that he could work at a series of menial restaurant and handyman jobs while he improved his English. Life was difficult and jobs were scarce, though he did manage to keep a chicken in his room for a while. A charitable local minister he met through his uncle found him a place as a student at the prestigious Peddie School, in Hightstown, New Jersey (not far from Princeton), where he worked hard and did well, but upon graduation, his education at first seemed to be of little use–his uncle had returned to Bulgaria, and there were no more family funds forthcoming. He was homeless for a while, working temporary jobs, but then he related his tale to a Baptist minister named Cooke, who encouraged him to seek the aid of various local congregations. Once he had accumulated $200 in savings and gifts, Pastor Cooke helped him find a spot at Colgate, at that time a Baptist-affiliated college.At Colgate, John met the sister of two brothers who were fellow students, a girl named Iva Purdy, a descendant of early settlers in Connecticut and generations of farmers in upstate New York. Iva, herself a high school graduate with a talent for mathematics, was teaching in a nearby school. After courting Iva, John married her at Christmas 1900 and then graduated from Colgate the following June. John Vincent was born on October 4, 1903.Although John had taken his degree in philosophy, he found work in industrial engineering at the Edison power plant in Orange, New Jersey. When work at the plant (possibly chemicals used in the manufacture of lightbulbs) seemed to be adversely affecting his health, he moved on to the power plant in Utica, New York, then to the Delaware, Lackawanna, and Western Railroad electrical plant in Hoboken, New Jersey. At night, he took correspondence courses in electrical engineering. Four children had been born by the time John Vincent was nine–two who lived and two who died in infancy. John and Iva came to feel that the family was not thriving because, in addition to John’s own respiratory problems, the children were suffering repeated bouts of illness. They decided to move to the newly founded town of Brewster, Florida, on the west coast, some thirty miles as the crow flies southeast of Tampa, where American Cyanamid was in the process of exploiting local phosphate deposits. John got a good job, and the children’s health improved. John Vincent attended school at the local two-room schoolhouse.Iva Atanasoff gave her oldest child considerable freedom, both of action and of thought, in part because other children were born in Florida (eventually there were seven) and she oversaw a large garden in addition to the household. But Iva also retained her interest in intellectual pursuits–according to family stories, she liked to sit in her rocking chair and read while John and his younger brothers and sisters played about her. By the time young John got to school, he already knew how to read and calculate, and at first he was a difficult pupil–he was used to following his own agenda. Since he had no trouble doing his work, he finished ahead of the other children, and once he had done so, he made himself a “pest,” according to his younger sister. But he was an inconvenient pupil also because he was inquisitive and knew more than many of his teachers. He was easily offended, especially by teasing and slurs, and he didn’t mind getting into fights. Some teachers handled him well and some did not, but however they handled him, his pronounced eagerness to learn persisted–he eagerly explored both the countryside and whatever books he could get hold of.In 1913, when he was not quite ten, John helped his father wire their home for electricity (subsequently, they wired the homes of some of their neighbors, too). In 1914, John mastered the owner’s manual of his father’s new Ford Model T, and at eleven he was driving it. John read his mother’s books, including Ruskin and Spenser, and he read his father’s books–including a manual on radiotelephony (wireless sound transmission). When his father ordered an up-to-date slide rule, then decided that he didn’t really need it, John mastered it within a couple of weeks and thereupon became, in his own mind, a nascent mathematician. He found his father’s old college algebra textbook and began to work his way through it. What he could not understand (differential calculus, infinite series, logarithms) Iva explained to him. During this period, he learned about various number systems other than the decimal system–this unusual familiarity with nondecimal ways of counting and calculating and his practice using them was what would eventually distinguish his ideas about calculators from those of his contemporaries.John liked to make things and to demonstrate his skills–in sixth grade, because some older girls who had already finished elementary school were gathering in the back of the classroom and crocheting, he learned to crochet. He pursued his project at school, no longer undaunted by teasing but stimulated by it–he flaunted his work and bragged about his skills until the teacher banned crocheting at school. He soon learned to sew. In fact, John Vincent Atanasoff seemed to see every new idea or object as an opportunity to explore and master whatever his world had to offer. Atanasoff’s parents gave him plenty of freedom, encouraged his enterprise, and helped him pursue what he wanted to master. They also made a stable life for him in an out-of-the-way spot where there was plenty to do and plenty of space to do it in.The Atanasoffs’ life in Brewster was not untroubled–the Atanasoff family, with its strange name and alien ways, was sometimes harassed and their property vandalized. John Atanasoff encountered resentment at work. The larger culture seethed with prejudice and vigilantism. A local Catholic lawyer was run out of the area. Between 1909, when the Atanasoffs arrived in Brewster, and 1920, more than fifty black people were lynched in Florida–Atanasoff himself remembered witnessing a lynching as a teenager, in Mulberry (about eleven miles north of Brewster), though that one is not attested to in Ralph Ginzburg’s 100 Years of Lynchings.In 1912, John and Iva purchased a 155-acre farm southwest of Brewster, which included a 30-acre orange grove and 120 acres of timber. For young John, the farm meant more scope for exploration and, in particular, endless chances to not only repair the machinery used on the farm, but to take it apart and improve its design. The boy became interested in farming itself–he subscribed to Wallaces’ Farmer (the publication founded in Iowa by the grandfather of Vice President Henry A. Wallace) and tried the latest farming techniques. Since John Atanasoff worked full time, young John became the one who organized and ran the farm. In the meantime, he graduated from the high school in Mulberry, completing his coursework in two years, at fifteen. The teachers at the high school did not attempt to control Atanasoff’s independence or restrict his education–they encouraged his curiosity and his enterprise. Once he had graduated, Atanasoff got himself certified to teach math classes and saved the money he earned toward his college education, which he already knew would be in math and science. He worked for a year as a phosphate prospector and entered the University of Florida in 1921, just before his eighteenth birthday.The University of Florida is and was a land-grant university. The Morrill Act of 1862, under which both the University of Florida and Iowa State College were founded, was written for a specific educational purpose: “to teach such branches of learning as are related to agriculture and the mechanic arts, in such manner as the legislatures of the States may respectively prescribe, in order to promote the liberal and practical education of the industrial classes in the several pursuits and professions in life.” In other words, the land-grant colleges were intended to focus on the useful. In what is perhaps the paradigm of public higher education, the three state-funded colleges in Iowa are an example of this idea of the distinct (and class-based) purposes of higher education: postgraduate degrees are offered by the medical school, the art school, the music school, the graduate school, the law school, and the business school at the University of Iowa. Postgraduate degrees in engineering, agriculture, veterinary medicine, design, and industrial engineering are offered at Iowa State (though these categories have gotten somewhat less distinct in the last twenty-five years). The third state-funded school was, until 1961, Iowa State Teachers College, a normal school. Although the system of higher education was not as distinct in every state as it was in Iowa (the University of Wisconsin and the University of Minnesota have all types of programs on the same campus), the land-grant colleges retained their focus on disciplines applicable to the health and wealth of the individual states. The Morrill Act promised to fund these colleges by granting each state thirty thousand acres of federal land, the proceeds of which would go to the colleges. The land did not have to be inside the state–New York State was granted land in Wisconsin, for example.The Morrill Act did not originally cover Florida, because the Confederate states had seceded from the Union before the passage of the act, but the act was extended in 1890 to the former Confederate states. Most of these states used money from the act to fund the useful arts at the main campus and to fund the establishment of separate, segregated black colleges. In 1905, Florida Agricultural College, in Lake City, was moved fifty miles south to Gainesville and renamed the University of the State of Florida. At the time of John Vincent Atanasoff’s matriculation, the university was all male and all white–women students went to Florida Female College, in Tallahassee, and black students of both sexes went to Florida Agricultural and Mechanical College for Negroes, also in Tallahassee. Related to the Morrill Acts of 1862 and 1890 was the Hatch Act of 1887, which funded (also through land grants) the establishment of agricultural experiment stations in each of the states. These stations were normally attached to the land-grant colleges, broadening their practical mandate.By the time he began college, Atanasoff knew he wanted to study physics and to be a physicist. He was familiar with and excited by Einstein’s theories and by the other work being done in the field, but no physics major was offered at the university, so he went into electrical engineering, the most theoretical scientific major offered. In Gainesville, Atanasoff was surrounded by opportunities to think, but also opportunities to do. Requirements of the electrical engineering major included building models and projects, so Atanasoff took classes in machine shop, forge and foundry, and electrical mechanics. He also pursued his earlier interest in radio communication. He tutored students for money and worked summers–one summer in Jacksonville, he found a lucrative job surveying the city streets. He was, in short, brilliant, eager, enterprising, highly directed, and hardworking. Just as John Atanasoff’s life had been almost a paradigm of the classic immigrant story, John Vincent Atanasoff’s life was almost a paradigm of the classic ambitious American tale–a Tom Sawyer-like boyhood followed by a Horatio Alger-style self-funded and successful career.But the elder Atanasoff’s life remained difficult–while John Vincent was away in Gainesville, John and Iva decided to sell the farm and move to Bradley Junction, a town between Brewster and Mulberry. One night when John was coming home, he was attacked by a mob clad in white robes and nearly killed. He was saved by the wife of the Cyanamid plant manager, who heard the ruckus and ran outside with a shotgun. The mob was revealed to be made up, in part, of neighbors whose children Iva tutored in math and, in part, men who worked for John at the plant, all apparently motivated by the strangeness of John’s name and origins. The attackers broke John’s leg and ribs, and there were so many internal injuries that John was bedridden for weeks; John Vincent had to return from college to help take care of him. Although the attack was foiled, the younger Atanasoff children suffered for years from the xenophobia, and probably the envy, of the local population. Read more

Reviews from Amazon users which were colected at the time this book was published on the website:

⭐A commentaryI REALLY do not want to get into the ripe tomato throwingcontest of “Who Invented … “. The protagonistsusually ignore various relevant conditions.1) There is an attempt in the patent procedure to verify that the patent applicant is in fact “the inventor” – in part, this is the reason for “disclosure of prior art” – to help the patent office with this verification. BUT – the above, although necessary, is not sufficient, – including timely filing – Mauchly – paying all the fees – Iowa State – not diddling too much with the process to your advantage – ala Lemelson ;-)) There is no question by anyone that the ENIAC patent application was filed after the required date !! There were confusing circumstances Moore School, Army, Security, … but – There is probably no argument that Atanasoff supplied patent information to Iowa State, a/the major stake holder, and patent attorney which let the patent process lapse.2) The lack of a patent is almost irrelevant (in my view) to actual invention Many great inventions, from acclaimed inventors, had no patent example – Ben Franklin, ( no slouch at acquiring money, self financed ambassador to England and later France)specifically gave his lightning rod and efficient stove to the public by not patenting those very useful devices :-)) Other actual inventors/innovators have been stripped of patent rights on procedural grounds – * No one * argues that ENIAC was not very innovative !! and it did the intended task very well :-))3) In a patent trial, the protagonists should try to be credible. By his own admission, Mauchly intended to be “forgetful” – and was tripped up – in court – multiple time by the other side. This is not likely to impress to any judge who also likely resents- the violation of the witnesses oath – skating on or actual perjury – – the intentional waste of the court’s time.4) And what is a “computer” anyway ? assuming we ignore humans, what adjectives do we throw into the fray?? – “Electronic” ?? – why be restrictive ?? – “Stored Program” ?? – and the original ENIAC wasn’t – – is the later capability of executing function switch settingsas instruction legal as “stored”? – “Turing Complete” ?? – … – “Index Registers” ?? – “unthinkable without ;-)” currently – “Able to Run Flight Simulator” ?? – OK – just teasing – So, if you refuse to pick your set of adjectives, why get into a discussion/argument – unless you love throwing ripe tomatoes -I’ve been very interested in the ABC machine […] and many other machines […] […] […] […] […]for a few years.John Gustafson recommended I read Smiley’s “The Man Who Invented The Computer”.I replied that a book with that title was too silly to bother with.John persisted, saying that the title wasimposed by the publisher, that a better title would be “The Men Who Invented The Computer”.With that qualification I read the sample on Amazon,found the sample not bad, and that John had written the appendices.I complained that the author seemed not a “computer techie” – the Babbage Difference Engine(s) designs are NOT analog.John said that he must have missed that in proof reading/correcting the book.So I ordered the book out of courtesy/curiosity.While waiting, I refreshed my memory with two Atanosoff/ABC books.”The First Electronic Computer: The Atanasoff Story” by the two Burks”Atanasoff: Forgotten Father of the Computer” by Mollenhoff And read on-line oral histories […]and on-line Amazon reviews.One of those reviews prompted me to re-read chapter eight in “ENIAC” by McCartney -of “The Trial”. I would think all sides would be satisfied,given the specifics of U.S. patent law – which many protagonists ignore.An aside – about 8 years ago, Mauchly’s widow”Kay” McNulty Mauchly Antonelli spoke at a “Women in Computing”presentation at Mills College. A charming lady,who had been one of the original programmers of the ENIAC.When I asked her of her view of Atanasoff, she replied”We do not mention that name in our home.”She said she had never seen Monterey California, so I offered to show her that beautiful place – Unfortunately, the next day, her daughter had a bad cold, so Kay phoned to cancel. :-((Ah – the book – has arrived -Rather folksy – easy reading – lots of details of lots of the computer “inventors”.One of the reviewers complained of no citations.Indeed – there were no little superscript numbers. ( Instead of the superscripts, to signal you in the text, there are page numbers with quoted text with citations in “Notes” at the end of the book. I prefer the little numbers.)I appreciated the author’s comparison of the lives of the various people involved with trying to solve computational problems from about 1935 to 1948 using machinery.A was doing this while B was doing that.I had read individual biographies without comparing their lives and problems in time line.Reading the last part of the book is disturbing.It attempts to describe the swirling acrimonious confusing turbulencesurrounding who (if any “ONE”) “invented” the “computer”.One wonders if the world would have been amore pleasant place if: a) we agree to define “computer”, with a selection of appropriate adjectives such as “stored program”, “electronic”, “general purpose”, … b) if Babbage had patented his ideas c) if Zuse’s German patent had been more quickly widely known. d) if Iowa State had paid the patent attorney to file Atanosoff’s patent application. e) … x) we all understand U.S. patent law better. y) … z) we try to solve today’s problemsThe author took on a formidable/impossible task – I think succeeded rather well for a general audience book.I’ll give a 4 rating – probably not 3+ , even though I’m a techie.

⭐This book is pretty tough reading. I don’t mean that the technical subject matter is tough to read about, though it is somewhat challenging. Rather, the toughness stems, I think, from a simple fact: Jane Smiley is a novelist– and an excellent one, too– but writing nonfiction requires a different skill set.I’ll just ignore all of the claims about the book’s alleged errors and the author’s supposed biases; they’ve been dealt with at considerable length in other reviews, so I think that those dead horses has been beaten sufficiently. It’s clear to me that the modern computer had many parents. The book is about the claim of one particular parent that his work was essentially stolen by another particular parent. A federal court decision resolved that issue in the early 1970s, and since that decision was never appealed, it still stands.Smiley spends most of the book describing the efforts of a few of the computer’s parents, and she agrees with the eventual court decision as to who “invented” the computer. However, her own account makes it very clear that, despite her conclusion, there actually was no single inventor. Rather, the computer evolved as numerous people worked to create workable machines, mostly in order to further their nations’ efforts in World War II.Smiley runs aground by attempting to combine an essentially historical account of the evolution of technical developments with a character-driven narrative centered on her protagonist, John V. Atanasoff. For me, it just didn’t work well. There are too many attempts to look into the motives and emotions of the central characters, and these inferences don’t further the technical account at all. In short, she seems to have written two books at once and attempted to merge them.The result for me was that I really didn’t know the characters much better than I did when I started the book, and I really didn’t have a much better grip on the nature of the early computers, either.Bottom line: It’s OK, but there’s a better book about this subject yet to be written.

⭐Excellent – riveting to read, giving the larger context of the work other persons were doing on similar computer development at the time of 1920 through 1950, and clearly showing that the actual digital systems for software and hardware we use today were from the work of John V. Atanasoff at Iowa State University, in Ames Iowa, NOT the ENIAC machine at the University of Pennsyvania.

⭐This was a good read. However, I’m more of the opinion that Konrad Zuse of Germany was first. However, Zuse is overlooked since he was a German citizen in Nazi Germany when he was inventing this computer. [The good news is Zuse’s computers weren’t co-opted by the Nazi military.]It is too bad that the University destroyed Anastoff’s invention. Fairly happy with this purchase!

⭐This book is titled as a biography of just one of the pioneers of early digital computers, JV Atanasoff who built the ABC at Iowa State College in the late 1930s/early 1940s, and was subsequently named in a US court action as the inventor of electronic computing. As you would imagine of a book written by a prize-winning novelist, the story is told in finely crafted prose, and in sufficient detail to give a flavour of the achievement without it being a texbook of computer science. What isnt obvious from the subtitle is that the author spends an appropriate amount of time putting Atanasoff’s work in context with the life and work of other computer pioneers such as the originally lauded inventors of the digital computer Mauchly and Eckert,the British Bletchley Park duo of Turing and Flowers, and other originals such as John Von Neumann and Konrad Zuse. For each scientist Smiley gives a really evocative pen picture of their characters, their backstories and relays some detail of their work.This is a fine book, which I finished after a couple of days of enjoyable reading (it is about 200 pages long), and I would recommend it to anyone interested in finding out about the people who were working on the original electronic computers and how their stories are interlinked.

⭐I liked lots about this book – it looked at developments in computers in Germany the US and the UK, for a start, and explained why computers were becoming so necessary by the 1930’s. There were telling asides about the importance of those with central European origins who made important contributions, and the crass way the British Government shot the nascent British computer industry in the foot, and the growth and importance of Land Act universities in the States, and, and………

⭐This is an easy to read, captivating biography about an inventor (and his student and co-inventor Berry) whose name is often passed over in the writings of the history of early computers. Especially interesting is the story about the ENIAC co-inventor J. Mauchly and what he really took home after spending some time looking at the ABC computer (and squeezing J. Antanasoff for information).
