Gerrit Blaauw
From Wikipedia, the free encyclopedia
Gerrit Anne (Gerry) Blaauw (b. July 17, 1924, The Hague, Netherlands; Ph.D. Harvard, 1952) is one of the principal designers of the IBM System/360 line of computers, together with Fred Brooks, Gene Amdahl, and others.
In 1949, he won an exclusive scholarship funded by IBM Chief Executive Officer Thomas J. Watson. After an initial year at De la Fayette University in Pennsylvania, Blaauw studied at Harvard University with Howard Aiken, inventor of the early Mark I computer. At Harvard, he worked on design of the Mark III and Mark IV computers. Blaauw also met Fred Brooks there.
After graduation, Blaauw returned to the Netherlands, but in 1955 came back to the United States to work at IBM's Poughkeepsie labs. He worked with Brooks on a number of projects:
- He was a designer on the IBM 7030 STRETCH project.
- He worked on the ill-fated IBM 8000 series, and in particular designed a paging system for the IBM 8106 in the 1960-1961 period.[1]
- He was a key engineer on the IBM System/360 project, announced in 1964. Among other contributions, Blaauw made the successful case for an 8-bit (as opposed to 6-bit) design.
- He designed a revolutionary address translation system, the "Blaauw Box", part of the original design of the important IBM System/360-67. This system proved the first practical implementation of virtual memory.
After leaving IBM, Blaauw became a computer science professor in the Netherlands. He retired in 1989 as professor emeritus with Twente University. In 1997 he co-authored a computer architecture book with Brooks.
