Günter Lumer

Günter Lumer (1929–2005) was a mathematician known for his work in functional analysis. He is the namesake of the Lumer–Phillips theorem on semigroups of operators on Banach spaces, and was the first to study L-semi-inner products. Born in Germany and raised in France and Uruguay, he spent his professional career in the United States and Belgium.[1]

Lumer was born in Frankfurt, Germany, on May 29, 1929. His family fled the Nazis in 1933, moving to France and then again in 1941 to Uruguay, where he became a citizen. Lumer studied at the Universidad de la República, where he came under the influence of Paul Halmos; his first mathematics paper, published in 1953, was jointly authored by Halmos and Juan Jorge Schäffer. He completed a degree in electrical engineering at Montevideo in 1957, and traveled to Halmos' home institution, the University of Chicago, on a Guggenheim Fellowship.[1] At Chicago, he completed a doctorate in 1959 under the supervision of Irving Kaplansky.[1][2]

Following short-term positions at the University of California, Los Angeles and Stanford University, he joined the faculty at the University of Washington in 1961. He moved to the University of Mons-Hainaut in 1973, and then to the International Sovlety Institutes for Physics and Chemistry in Brussels in 1999, where he remained until his death in 2005.[1]
