The IEEE Computer Society traces its origins to the 1946 formation of the Subcommittee on Large-Scale Computing of the American Institute of Electrical Engineers (AIEE). Five years later, the Institute of Radio Engineers (IRE) formed its Professional Group on Electronic Computers. The principal volunteer officers of both these groups were designated chairs. The AIEE and the IRE merged in 1963 to become the Institute of Electrical and Electronics Engineers (IEEE). The respective committee and group of the predecessor organizations combined to form the modern IEEE Computer Society. The society's principal volunteer officer has been designated as president since 1970. The Computer Society celebrates its fiftieth anniversary year in 1996
