"Bo" joined IBM in 1951 as a junior engineer working on the IBM-701 (Defense Calculator), and had various responsibilities through 1962 when he was appointed vice president for the Data Systems Division, developing the System/360. In 1961, only 10 years after joining IBM, he almost single-handedly persuaded management to abandon a less ambitious product plan for one that resulted in the IBM System/360. He demonstrated a model of the IBM System/360 on April 7, 1964, the day the system was announced. In 1985, Bo Evans, Fred Brooks, and Eric Bloch received the National Medal of Technology at a White House ceremony for their work in developing the IBM System/360, described as "revolutionizing the industry."

"I am the luckiest person in the world to have worked at IBM during the time of its entry into electronic computing, and to be part of the computer industry in those most exciting years."
