Concepts familiar from grade-school algebra have broad ramifications in computer science.
Hugo Logemann, an engineer who helped develop radar at MIT during World War II, died Dec. 2 after a brief illness. He was 89.
Born and raised in Milwaukee, Logemann graduated in 1942 with a bachelor's degree in electrical engineering from the University of Wisconsin, Madison. Shortly thereafter, he joined the Radiation Laboratory at MIT, where he worked on designing radar systems.
When the Radiation Laboratory disbanded after the end of the war, Logemann went to work at the University of Rochester before rejoining the MIT community as a technical staff member in Lincoln Laboratory. As part of his duties at Lincoln Lab, Logemann was involved in the MTI (Moving Target Indicator) activity and also worked on radar receivers.
Logemann left Lincoln Lab in 1956 to pursue a career with RCA.
Logemann was named a Lifetime Fellow of IEEE in 2002 for his contributions to radar detection and reception and to the development of related instrumentation.
Logemann is survived by his wife, Pennie; a daughter, Lois Whitney; and two grandchildren.
A memorial service was held at 2 p.m. Monday, Dec. 15, at First Parish in Concord. Contributions in his memory may be made to the Concord Public Library, 129 Main St., Concord, MA 01742.
