On This Day in History and Fiction
1764: Satirist, painter, illustrator, and critic William Hogarth dies. His work ranged from realistic portraiture to comic strip-like series of pictures called "modern moral subjects".
1849: Mathematician and academic Ferdinand Georg Frobenius born. He will make contributions to the theory of elliptic functions, differential equations, and group theory.
1923: Mathematician and electrical engineer Charles Proteus Steinmetz dies. He fostered the development of alternating current, formulating mathematical theories which advanced the expansion of the electric power industry in the United States.
1945: Mathematician and naval engineer Aleksey Krylov dies. Fame came to him in the 1890s, when his pioneering theory of oscillating motions of the ship became internationally known.
1972: Aircraft designer Igor Sikorsky dies. He pioneered both helicopters and fixed-wing aircraft.
1972: Space pilot and alleged time-traveler Henrietta Bolt remembers aircraft engineer Igor Sikorsky as "a genius, and a true friend."
1983: Mathematician and philosopher Alfred Tarski dies. He was a prolific author, contributing to model theory, metamathematics, algebraic logic, abstract algebra, topology, geometry, measure theory, mathematical logic, set theory, and analytic philosophy.
