Why Is Helmut H. Schaefer Influential?

(Suggest an Edit or Addition)

According to Wikipedia, Helmut Heinrich Schaefer was a German mathematician, who worked primarily in functional analysis. His two best known scientific monographs are titled Topological Vector Spacess and Banach Lattices and Positive Operators . 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.
