Shmuel Friedland
Shmuel Friedland (born 1944 in Tashkent, Uzbek Soviet Socialist Republic)[1] is an Israeli-American mathematician.
Friedland studied at the Technion – Israel Institute of Technology, graduating in 1967 with bachelor's degree and in 1971 with doctorate of science under the supervision of Binjamin Schwarz.[2] As a postdoc Friedland was in 1972/73 at the Weizmann Institute, in 1973/74 at Stanford University, and in 1974/75 at the Institute for Advanced Study. Then he taught at the Hebrew University of Jerusalem, where he became in 1982 a full professor. In 1985 he became a professor at the University of Illinois at Chicago.[3]
Besides linear algebra (matrix theory), Friedland does research on a wide variety of mathematics, including complex dynamics and applied mathematics. With Elizabeth Gross, he proved a set-theoretic version of the salmon conjecture posed by Elizabeth S. Allman.[4]
With Miroslav Fiedler and Israel Gohberg, Friedland shared in the first Hans Schneider Prize, awarded by the International Linear Algebra Society in 1993. He was elected a Fellow of the American Mathematical Society (Class of 2019).

gollark: Presumably which apartment in a building someone is in is available information to people configuring elevators there.
gollark: Sure it would. None are safe.
gollark: It would be boring and easy for those.
gollark: The elevator should just pick a floor at random then convince the passengers they need to go there.
gollark: Alternatively, have buttons, but instead of you pressing them it just uses a camera and gaze tracing to determine which you want.
