Bob Bemer

Template:Short description Template:Infobox scientist Robert William Bemer (February 8, 1920 – June 22, 2004) was a computer scientist best known for his work at IBM during the late 1950s and early 1960s.<ref name="thocp">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Early life and education

Born in Sault Ste. Marie, Michigan, Bemer graduated from Cranbrook Kingswood School in 1936 and took a Bachelor of Arts (B.A.) in mathematics at Albion College in 1940. He earned a certificate in aeronautical engineering at Curtiss-Wright Technical Institute in 1941.

Career

Bemer began his career as an aerodynamicist at Douglas Aircraft Company in 1941, then worked for RAND Corporation from 1951, IBM from 1957, UNIVAC – Sperry Rand in 1965, Bull from 1965, General Electric from 1970, and Honeywell from 1974.<ref name="Bemer_Resume">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

He served on the committee which amalgamated the design for his COMTRAN language with Grace Hopper's FLOW-MATIC and thus produced the specifications for COBOL. He also served, with Hugh McGregor Ross and others, on the separate committee which defined the ASCII character codeset in 1960, contributing several characters which were not formerly used by computers including the escape (ESC), backslash (\), and curly brackets ({}).<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> As a result, he is sometimes known as The Father of ASCII.<ref name="thocp"/> In 2000, Bemer claimed to have proposed the term octet (rather than Werner Buchholz' byte) while heading software development at Cie. Bull, France, between 1965 and 1966.<ref name="Bemer_2000"/> He also proposed the term hextet for 16-bit groups.<ref name="Bemer_2000"/>

Bemer is probably the earliest proponent of the software factory concept. He mentioned it in his 1968 paper "The economics of program production".<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Other notable contributions to computing include the first publication of the time-sharing concept in 1957 and the first attempts to prepare for the Year 2000 problem in publications as early as 1971.<ref>Template:Cite journal</ref> Acting in an advisory capacity, Bob and Honeywell employees Eric Clamons and Richard Keys developed the Text Executive Programming Language (TEX).<ref>Template:Cite journal</ref>

In the late 1990s, as a retiree, Bob invented an approach to Year 2000 (Y2K) date conversion, to avoid anticipated problems when dates without centuries were compared in programs for which source code was unavailable. This involved detecting six and eight character operations at runtime and checking their operands, adjusting the comparison so that low years in the new century did not appear to precede the last years of the twentieth century.

Death

Bemer died at his home in Possum Kingdom Lake, Texas in 2004 at age 84 after a battle with cancer.<ref>Template:Cite news</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>Template:Cite news</ref><ref>Template:Cite news [1]Template:Dead linkTemplate:Cbignore</ref>
