Theodore von Kármán (von Sköllöskislaki Kármán Todor) (May 11, 1881 - May 6, 1963) was an engineer and physicist who was active primarily in the fields of aeronautics during the seminal era in the 1940s and 1950s. He is personally responsible for many key advances in aerodynamics, notably his work on supersonic and hypersonic airflow characterization.

He was born in Budapest, Hungary as Kármán Tódor, studied engineering at the city's Royal Technical University, graduating in 1902. He then joined Ludwig Prandtl at the University of Göttingen, and received his doctorate in 1908. He taught at Göttingen for four years. He became fascinated by flight, and in 1912 took a job as director of the Aeronautical Institute at the University of Aachen. He stayed there until 1930 (interrupted by service in the Austro-Hungarian army 1915-1918, where he designed an early helicopter).

Apprehensive about developments in Europe, in 1930 he accepted the directorship of the Guggenheim Aeronautical Laboratory at the California Institute of Technology and emigrated to the United States. In 1936, with Frank Malina he founded a company Aerojet to manufacture JATO rocket motors.

In 1944 he helped found the Jet Propulsion Laboratory (now a part of NASA), and became the first chairmain of the Scientific Advisory Group in 1946, which studied aeronautical technologies for the Army Air Force. He also helped found AGARD, the NATO aerodynamics research oversight group (1951), the International Council of the Aeronautical Sciences (1956), the International Academy of Astronautics (1960), and the von Karman Institute in Brussels.

Kármán's fame was in the use of mathematical tools to study fluid flow, and the interpretation of those results to guide practical designs. He was instrumental in recognizing the importance of the swept-back wings that are ubiquitous in modern jet aircraft.

Specific contributions include theories of non-elastic buckling, unsteady wakes in circum-cylinder flow, stability of laminar flow, turbulence, airfoils in steady and unsteady flow, boundary layers, and supersonic aerodynamics.

He made additional contributions in other fields, including elasticity, vibration, heat transfer, and crystallography. His name appears in at least the following concepts: Template:Wikiquote

Craters on Mars and the Moon are named in his honor.
