Charles William "Charlie" Bachman III (born December 11, 1924) is an American computer scientist, who spent his entire career as an industrial researcher, developer, and manager rather than in academia. He is particularly known for his work in the early development of database management systems. His techniques of layered architecture include his namesake Bachman diagrams.
Charles Bachman was born in Manhattan, Kansas in 1924, where his father, Charles Bachman Jr., was the head football coach at Kansas State College. He attended high school in East Lansing, Michigan.
In World War II he joined the United States Army and spent March 1944 through February 1946 in the South West Pacific Theater serving in the Anti-Aircraft Artillery Corps in New Guinea, Australia, and the Philippine Islands. There he was first exposed to and used fire control computers for aiming 90 mm guns.
After his discharge in 1946 he attended Michigan State College and graduated in 1948 with a bachelor's degree in Mechanical Engineering where he was a member of Tau Beta Pi. In mid-1949 he married Connie Hadley. He then attended the University of Pennsylvania. In 1950, he graduated with a master's degree in Mechanical Engineering, and had also completed three-quarters of the requirements for an MBA from the university's Wharton School of Business.
Bachman spent his entire career as a practicing software engineer or manager in industry rather than in academia. In 1950 he started working at Dow Chemical in Midland, Michigan. In 1957 he became Dow's first data processing manager. He worked with the IBM user group SHARE, on developing new version of report generator software, which became known as 9PAC. However, the planned IBM 709 order was cancelled before it arrived. In 1960 he joined General Electric, where by 1963 he developed the Integrated Data Store (IDS) one of the first database management systems using what came to be known as the navigational database model in the Manufacturing Information And Control System (MIACS) product. Working for customer Weyerhaeuser Lumber, he developed the first multiprogramming network access to the IDS database, an early online transaction processing system called WEYCOS in 1965. Later at GE he developed the "dataBasic" product that offered database support to the Basic language timesharing users. In 1970, GE sold its computer business to Honeywell Information Systems, and so he and his family moved from Phoenix, Arizona to Lexington, Massachusetts. In 1981, he joined a smaller firm, Cullinane Information Systems (later Cullinet), which offered a version of IDS that was called IDMS and supported IBM mainframes.
