John Atanasoff

Few would deny that the invention of the computer has revolutionized society or that the world of today would look quite different without computers. In the relatively short span of time that has elapsed since the world's first electronic digital computer was invented in 1939, computers have become universal tools that are an integral part of modern life. Yet, comparatively few people know that John Atanasoff, the genius who invented the first computer and initiated the computer revolution, was of Bulgarian ancestry. John Atanasoff was a prominent American inventor who took pride in his Bulgarian heritage and maintained strong ties to his ancestral home of Bulgaria.

John Atanasoff's father, Ivan Atanasoff, was born in the village of Boyadjick, Bulgaria. Ivan Atanasoff had lost his own father in 1876, when the latter was brutally killed in the April Uprising of the Bulgarians against the Ottoman Empire. In 1889, when Ivan Atanasoff was thirteen years old, he emmigrated to the United States accompanied by an uncle. He later married Iva Lucena, a mathematics teacher. John Vincent Atanasoff was born in the town of Hamilton, New York on October 4, 1903. After John's birth, the Atanasoff family moved a number of times as Ivan Atanasoff sought better employment in several different electrical engineering positions. They eventually settled in Brewster, Florida, where John completed grade school. The Atanasoff home in Brewster was the first house the family had lived in that was equipped with electricity. By age nine, John had taught himself how to repair faulty electric wiring and light fixtures on their back-porch.

It was recognized early that John Atanasoff had both a passion and talent for mathematics. His youthful interest in baseball was quickly forgotten once his father showed him the logarithmic slide rule he had bought for facilitating engineering calculations. The slide rule completely captivated the nine-year-old boy, who spent hours studying the instructions and delighting in the fact that this mathematical tool consistently resulted in correct solutions to problems. Young John's obsession with the slide rule soon led to a series of discoveries on the logarithmic principles underlying slide rule operation and, subsequently, to a study of trigonometric functions. It was not long before the gifted youth had achieved substantial progress in his math studies. At this time John's mother introduced him to counting systems and number bases other than base ten, including an introduction to the binary system which would prove important in his later work.

John Atanasoff completed his high school course in two years, with excellence in both science and mathematics. He had decided to become a theoretical physicist, and with that goal in mind, entered the University of Florida in Gainesville in 1921. Because the university curriculum did not offer degrees in physics, John began his undergraduate studies in the electrical engineering program. The knowledge of electronics and higher math that John acquired as an electrical engineering student would later prove fortuitous in helping to transform the theory of the computer into a working reality

John Atanasoff graduated from the University of Florida in Gainesville in 1925, with a Bachelor of Science degree in electrical engineering. He received his Master's degree in mathematics from the Iowa State College in Ames, Iowa in 1926. After completing his graduate studies, Atanasoff accepted a position teaching physics and mathematics at Iowa State College. He was then accepted into the doctoral program at the University of Wisconsin, and received his doctoral degree (Ph. D.) in theoretical physics from Wisconsin in 1930. In his doctoral thesis, "The Dielectric Constant of Helium", Atanasoff was required to do many complicated and time consuming computations. Although he utilized the Monroe mechanical calculator, one of the best machines of the time, to assist in his tedious computations, the shortcomings of this machine were painfully obvious and motivated him to think about the possibility of developing a more sophisticated calculating machine. After receiving his Ph. D. in theoretical physics in July 1930, John returned to the staff of Iowa State College and began his work on developing a better and faster computing machine.
