List of Famous people who died in 1964

Heinrich Franz Friedrich Tietze was an Austrian mathematician, famous for the Tietze extension theorem on functions from topological spaces to the real numbers. He also developed the Tietze transformations for group presentations, and was the first to pose the group isomorphism problem. Tietze's graph is also named after him; it describes the boundaries of a subdivision of the Möbius strip into six mutually-adjacent regions, found by Tietze as part of an extension of the four color theorem to non-orientable surfaces.

Julius Bartels was a German geophysicist and statistician who made notable contributions to the physics of the Sun and Moon; to geomagnetism and meteorology; and to the physics of the ionosphere. He also made fundamental contributions to statistical methods for geophysics. Bartels was the first President of the International Association of Geomagnetism and Aeronomy (IAGA). With Sydney Chapman, he wrote the influential book Geomagnetism.

Ilka Grüning was an Austrian-Hungarian actress. Born in Vienna in the old Austrian-Hungarian Empire, she was one of many Jewish actors and actresses that were forced to flee Europe when the Nazis came to power in 1933. A respected and famous actress in Germany, she was forced to play bit parts in Hollywood.

Håkan Ingvar von Eichwald was a Finnish-Swedish bandleader and conductor. He led dance bands which featured some of Sweden's most prominent early jazz musicians, and later became a conductor of symphonic and operatic works.

Erich Eduard "Edi" Schönecker was an Austrian athlete, football (soccer) player, and architect. He competed at the 1908 Summer Olympics in London.

George Peter Lanyon was a Cornish painter of landscapes leaning heavily towards abstraction. Lanyon was one of the most important artists to emerge in post-war Britain. Despite his early death at the age of forty-six he achieved a body of work that is amongst the most original and important reappraisals of modernism in painting to be found anywhere. Combining abstract values with radical ideas about landscape and the figure, Lanyon navigated a course from Constructivism through Abstract Expressionism to a style close to Pop. He also made constructions, pottery and collage.
