Terry Welch
Terry Archer Welch (* 1939 , † 22. November 1988 in Travis County ) was an American computer scientist .
Welch studied electrical engineering at the Massachusetts Institute of Technology , where he also received his PhD. He then taught at the University of Texas at Austin , was a computer engineer at Honeywell in Waltham (Massachusetts) and from 1976 was manager for computer architecture research at the research center of the Sperry Corporation in Sudbury (Massachusetts) .
Welch developed the LZW algorithm, which is widely used in applications , based on the work of Jacob Ziv and Abraham Lempel from the 1970s. In 1983 he applied for a US patent for his employer (Sperry Corporation), the following year international patents; after it was granted, he published his algorithm. The algorithm was widely used, particularly in GIF format, on personal computers in the 1980s, which led to conflicts when Sperry (Unisys) began demanding license fees in 1994.
From 1983 he went to Digital Equipment Corporation as Senior Manager , for which he worked on advanced computer architectures at MMC (Microelectronics and Computer Technology Corporation), a joint research center established in 1982 for companies in the US computer industry.
He died of a brain tumor in 1988.
