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.
