Thomas Peterffy Biography

Thomas Peterffy was born in Budapest, Hungary on September 30, 1944. His parents were Hungarian aristocrats who had lost almost everything to the Soviet Union invasion. Peterffy was squeezed by a meager lifestyle and relentless oppression by the communist regime. 

By 1965, Thomas Peterffy left Hungary to join his father in the United States. In Hungary, he had received training as a surveyor and managed to land a job in an engineering firm in New York state. The company had just bought one of the first computers, an Olivetti No.1.

However, nobody at the company knew how to program their new computer. Peterffy volunteered, as he didn’t speak any English, he thought it might be easier to learn a programming language. The bet paid off, and Peterffy became a skilled programmer.
