Biography
Gary Kildall is 84 years old, an entrepreneur, from United States.
Gary Arlen Kildall (; May 19, 1942 – July 11, 1994) was an American computer scientist and microcomputer entrepreneur. During the 1970s, Kildall created the operating system CP/M among other operating systems and programming tools, and subsequently founded Digital Research, Inc. to market and sell his software products. He is considered a pioneer of the personal computer revolution.
In 1974 in Pacific Grove, California, Kildall demonstrated the first working prototype of CP/M, which would later become the dominant operating system for microcomputers for a time. Together with his invention of the BIOS (Basic Input Output System), his operating system allowed a microprocessor-based computer to communicate with disk storage. Kildall was among the earliest individuals to recognize microprocessors as fully capable computers.
During the 1980s, Kildall also appeared on PBS as co-host of Computer Chronicles, a weekly informational program that discussed the latest developments in personal computing.
