Victor (Viktor) Abramovich Zalgaller (Hebrew: ויקטור אבּרמוביץ' זלגלר; Russian: Виктор Абрамович Залгаллер) was a famous Russian-Israeli mathematician. He was born on December 25, 1920, and passed away on October 2, 2020. He made important discoveries in geometry and optimization. Zalgaller is especially known for his work on shapes like convex polyhedra, and for his studies in linear programming and dynamic programming. He also contributed to isoperimetry (the study of shapes with the same perimeter) and differential geometry.
