ever-more powerful encryption and decryption computers for the U.S. government.
By 1957 Isaac had had enough of working for others and struck out on his own. He then established the Auerbach Corporation for Science and Technology. Under the rubric of that corporation and independently, Isaac, as a pioneering entrepreneur in the computer field, founded and headed more than a dozen successful companies.
Among the best known of these was Auerbach Associates Inc., one of the earliest computer system design and consulting firms in the United States. Specializing in real-time systems, the firm was responsible for a new air-traffic control system for the Federal Aviation Administration, the earliest airline reservation system, and every computer in the U.S. Ballistic Missile Early Warning System. Personally, Isaac was a successful inventor, holding sixteen U.S. and foreign patents in the digital computer field.
Another firm that he founded, Auerbach Publishers Inc., produced a world-renowned series of loose-leaf information services covering computer technology, information management, and computers in manufacturing. These services updated information monthly and distributed it on six continents. The information eventually came to fill thirty-seven substantial binders, which essentially defined the computer industry.
As reflected in his consulting and his publishing, Isaac recognized how important communication among professionals was to the development of the information field. He pulled together forty-eight professional societies from fifteen countries and in 1960 founded (and served as the first president of) the International Federation for Information Processing. He was elected their first honorary life member in 1969.
Among Isaac's many other honors were his election as a fellow of the American Association for the Advancement of Science, a distinguished fellow of the British Computer Society (personally conferred by the Duke of Kent), a trustee of the Charles Babbage Institute, a fellow of the Institute of Electrical and Electronics Engineers, and an honorary member of the Information Processing Society of Japan.
