About
Helmut Heinrich Schaefer was a German mathematician at home on both sides of the Atlantic. His work centered on functional analysis. His two best known scientific monographs are titled Topological Vector Spaces (1966) and Banach Lattices and Positive Operators (1974). The first of these was subsequently translated into Spanish and Russian. The second made him an internationally recognized and leading scholar in this particular field of mathematics.
