William B. Johnson (mathematician)

William Buhmann Johnson ( born December 5, 1944 in Palo Alto, California) is an American mathematician.

William B. Johnson graduated in 1966 from his studies of mathematics at Southern Methodist University, he received his doctorate in 1969 with a thesis Operator and Dual Linear Topological Spaces operator Bases in James Dyer. From 1969 to 1971 he was assistant professor and then to 1973 lecturer at the University of Houston. He then served as a professor at Ohio State University until 1986, interrupted by stays at the University of Texas at Austin (1975 ), at the Hebrew University of Jerusalem ( 1976-1977 ) at the École polytechnique ( March and April 1980) and finally at Texas A & M University (Fall 1981). At this last station in 1984 he took a professorship, which he held until today. Other stays were California Institute of Technology (May and June 1989), Weizmann Institute of Science (January to March 1994), Mathematical Sciences Research Institute (Spring 1996) and again at the Weizmann Institute of Science (January to June 2002).

His main research area is the Banach space theory, but he also works in the non-linear functional analysis, probability theory and operator theory.

Johnson is a member of the American Mathematical Society and the Mathematical Association of America, and for a time co-editor of several well-known mathematical journals, including Transactions and Memoirs of the American Mathematical Society, Geometric and Functional Analysis, Mathematical Annals, and others. The Polish Academy of Sciences has awarded to him in 2007 by the Stefan Banach Medal.
