Hans F. Weinberger (September 27, 1928 in Vienna - September 15, 2017 in Durham, North Carolina)[1] was an Austrian-American mathematician, known for his contributions to variational methods for eigenvalue problems, partial differential equations, and fluid dynamics.
on the thesis Fourier Transforms of Moebius Series advised by Richard Duffin (1950).
During his tenure, Weinberger was very engaged in scientific life at the IMA, attending lectures and collaborating with visitors and postdocs.
His presence at these lectures usually meant that the toughest and most penetrating questions were asked.
While well known for his contributions to the analysis of partial differential equations, especially eigenvalue problems, Weinberger turned his attention to mathematical biology later in his career.
