  • 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 1947, he won an exclusive scholarship funded by IBM Chief Executive Officer Thomas J. Watson. After an initial year at Lafayette College 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 met Fred Brooks while he was working for IBM and visited Harvard, where Fred Brooks was then a graduate student. After graduation, Blaauw returned to the Netherlands where he worked on the second ARRA computer, 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. 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", which was removed from the original System/360 design, but was later used in IBM's proposal to Project MAC, and incorporated in the important IBM System/360-67. As implemented on the -67, this system became one of the first practical implementations of paged virtual memory – perhaps the first to be commercially practical. (The earlier Ferranti Atlas Computer was a seminal platform for paging research, but suffered from well-studied performance issues such as thrashing. ) The -67 was being used in commercial applications by 1968. After leaving IBM, Blaauw became a computer science professor in the Netherlands. He retired in 1989 as professor emeritus with Universiteit Twente. In 1997 he co-authored a computer architecture book with Brooks.
  • G.A. (Gerrit) Blaauw is een Nederlands natuurkundige en informaticus. Hij studeerde elektrotechniek aan de Harvard University, Cambridge Mass. in de Verenigde Staten en behaalde in 1949 zijn ingenieursdiploma (MSc); hij promoveerde in 1952 aan dezelfde universiteit. Van 1952 tot 1955 werkte hij bij het Mathematisch Centrum in Amsterdam, waar hij bijdroeg aan het ontwerp van de ARRA II, alleen in naam de opvolger van de ARRA I, de allereerste in Nederland gebouwde computer. Hij was ook betrokken bij het ontwerp van de FERTA-computer, wat eigenlijk gewoon een kopie van de ARRA II was, speciaal gemaakt voor Fokker. Van 1955 tot 1965 was hij mede-ontwerper van de architectuur van de IBM Systeem/360 mainframecomputer. Het model 67 was van zijn hand en werd bekend als de eerste computer die timesharing gebruikte, waarbij de computer schijnbaar gelijktijdig taken voor verschillende gebruikers verricht. Van 1965 tot 1989 was hij hoogleraar digitale technieken aan de Universiteit Twente. Blaauw is vooral bekend als Nederlands computerpionier. Hij is lid van de KNAW en buitenlands lid van de (US) National Academy of Engineering.
