John Vincent Atanasoff
Atanasoff was born on October 4, 1903 in Hamilton, New York to an electrical engineer and a school teacher. Atanasoff's father, Ivan Atanasoff was of Bulgarian origin, born in 1876 in the village of Boyadzhik, close to Yambol, then in Ottoman Empire. While Ivan was still an infant, Ivan's own father was killed by Ottoman soldiers after the Bulgarian April Uprising. In 1889, Ivan Atanasov immigrated to the United States with his uncle. Atanasoff's father later became an electrical engineer, whereas his mother, Iva Lucena Purdy (of mixed French and Irish ancestry), was a teacher of mathematics. Young Atanasoff's ambitions and intellectual pursuits were in part influenced by his parents, whose interests in the natural and applied sciences cultivated in him a sense of critical curiosity and confidence.
