Theodore von karman 1881 1963
Theodore von Karman (Hungarian: Szolloskislaki Karman Todor; May 11, 1881 – May 6, 1963) was a Hungarian-American mathematician, aerospace engineer and physicist who was active primarily in the fields of aeronautics and astronautics. He is responsible for many key advances in aerodynamics, notably his work on supersonic and hypersonic airflow characterization. He is regarded as the outstanding aerodynamic theoretician of the twentieth century.

Early life
Von Karman was born into a Jewish family in Budapest, Austria-Hungary as Karman Todor. One of his ancestors was Rabbi Judah Loew ben Bezalel. He studied engineering at the city's Royal Joseph Technical University, known today as Budapest University of Technology and Economics. After graduating in 1902 he moved to Germany and joined Ludwig Prandtl at the University of Gottingen, and received his doctorate in 1908. He taught at Gottingen for four years. In 1912 accepted a position as director of the Aeronautical Institute at RWTH Aachen, one of the country's leading universities. His time at RWTH Aachen was interrupted by service in the Austro-Hungarian Army 1915–1918, where he designed an early helicopter. He is believed to have founded the International Union of Theoretical and Applied Mechanics in September 1922 by organizing its first conference in Innsbruck. He left RWTH Aachen in 1930.
Emigration and JPL
Apprehensive about developments in Europe, in 1930 he accepted the directorship of the Guggenheim Aeronautical Laboratory at the California Institute of Technology (GALCIT) and migrated to the United States. In 1936, along with his graduate student Frank Malina and their experimental rocketry collaborator Jack Parsons, he founded a company Aerojet to manufacture JATO rocket motors. He later became a naturalized citizen of the United States.
He eventually became an important figure in supersonic motion, noting in a seminal paper that aeronautical engineers were “pounding hard on the closed door leading into the field of supersonic motion.”
German activity during World War II increased U.S. military interest in rocket research. During the early part of 1943, the Experimental Engineering Division of the United States Army Air Forces Material Command forwarded to von Karman reports from British intelligence sources describing German rockets capable of reaching more than 100 miles (160 km). In a letter dated 2 August 1943 von Karman provided the Army with his analysis of and comments on the German program.
In 1944 he and others affiliated with GALCIT founded the Jet Propulsion Laboratory (JPL), which is now a Federally funded research and development center managed and operated by Caltech under a contract from NASA. In 1946 he became the first chairman of the Scientific Advisory Group which studied aeronautical technologies for the United States Army Air Forces. 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 for Fluid Dynamics in Brussels (1956).
Last years
In June 1944, von Karman underwent surgery for intestinal cancer in New York City. The surgery caused two hernias, and von Karman's recovery was slow. Early in September, while still in New York, he met with U.S. Army Air Forces Commanding General Henry H. Arnold on a runway at LaGuardia Airport. Hap Arnold then proposed that von Karman move to Washington, D.C. to lead the Scientific Advisory Group and become a long-range planning consultant to the military. He returned to Pasadena around mid-September. Von Karman was appointed to the SAG position on October 23, 1944, and left Caltech in December 1944.
At age 81 von Karman was the recipient of the first National Medal of Science, bestowed in a White House ceremony by President John F. Kennedy. He was recognized, "For his leadership in the science and engineering basic to aeronautics; for his effective teaching and related contributions in many fields of mechanics, for his distinguished counsel to the Armed Services, and for his promoting international cooperation in science and engineering."
While on a trip to Aachen (Germany) in 1963, von Karman died. He is entombed in the mausoleum of Beth Olam Cemetery, in Los Angeles. He never married.
Von Karman'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.
Selected contributions
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 also appears in a number of concepts, for example:
