--- title: Theodore von Kármán - Wikipedia, the free encyclopedia date: 2007-02-27T06:11:51Z source: http://en.wikipedia.org/wiki/Theodore_von_Karman tags: novel_notes, science, history, physics --- **Theodore von Kármán** ([Hungarian][1]: _[Szőllőskislaki][2] Kármán Tódor_; May 11, 1881 – May 6, 1963) was a [Hungarian][3]-[American][4] [mathematician][5], [aerospace engineer][6] and [physicist][7] who was active primarily in the fields of [aeronautics][8] and [astronautics][9]. He is responsible for many key advances in [aerodynamics][10], notably his work on [supersonic][11] and [hypersonic][12] airflow characterization. He is regarded as the outstanding aerodynamic theoretician of the twentieth century.[[3]][13][[4]][14][[5]][15][[6]][16] ## Early life[[edit][17]] Von Kármán was born into a [Jewish][18] family in [Budapest][19], [Austria-Hungary][20] as Kármán Tódor. One of his [ancestors][21] was [Rabbi][22] [Judah Loew ben Bezalel][23].[[2]][24] He studied engineering at the city's Royal Joseph Technical University, known today as [Budapest University of Technology and Economics][25]. After graduating in 1902 he moved to [Germany][26] and joined [Ludwig Prandtl][27] at the [University of Göttingen][28], and received his doctorate in 1908. He taught at Göttingen for four years. In 1912 accepted a position as director of the Aeronautical Institute at [RWTH Aachen][29], one of the country's leading universities. His time at RWTH Aachen was interrupted by service in the [Austro-Hungarian Army][30] 1915–1918, where he designed an early [helicopter][31]. He is believed to have founded the [International Union of Theoretical and Applied Mechanics][32] in September 1922 by organizing its first conference in [Innsbruck][33].[[7]][34] He left RWTH Aachen in 1930. ## Emigration and JPL[[edit][35]] ![][36] Apprehensive about developments in Europe, in 1930 he accepted the directorship of the [Guggenheim Aeronautical Laboratory][37] at the [California Institute of Technology][38] (GALCIT) and migrated to the United States. In 1936, along with [Frank Malina][39] and [Jack Parsons][40], he founded a company [Aerojet][41] to manufacture [JATO][42] rocket motors. He later became a [naturalized citizen][43] of the United States. He later 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."[[8]][44] German activity during [World War II][45] 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][46] Material Command forwarded to von Kármán reports from [British][47] intelligence sources describing [German][26] rockets capable of reaching more than 100 miles (160 km). In a letter dated 2 August 1943 von Kármán provided the Army with his analysis of and comments on the German program.[[9]][48] In 1944 he and others affiliated with GALCIT founded the [Jet Propulsion Laboratory][49] (JPL), which is now a [Federally funded research and development center][50] managed and operated by Caltech under a contract from [NASA][51]. In 1946 he became the first chairman of the [Scientific Advisory Group][52] which studied aeronautical technologies for the United States Army Air Forces. He also helped found [AGARD][53], the [NATO][54] aerodynamics research oversight group (1951), the [International Council of the Aeronautical Sciences][55] (1956), the [International Academy of Astronautics][56] (1960), and the [Von Karman Institute for Fluid Dynamics][57] in [Brussels][58] (1956). ## Last years[[edit][59]] ![][60] In June 1944, von Kármán underwent surgery for [intestinal cancer][61] in [New York City][62]. The surgery caused two [hernias][63], and von Kármán'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][64] on a runway at [LaGuardia Airport][65]. Hap Arnold then proposed that von Kármán move to [Washington, D.C.][66] to lead the Scientific Advisory Group and become a long-range planning consultant to the military. He returned to [Pasadena][67] around mid-September. Von Kármán was appointed to the position on October 23, 1944, and left Caltech in December 1944.[[10]][68] At age 81 von Kármán was the recipient of the first [National Medal of Science][69], bestowed in a [White House][70] ceremony by President [John F. Kennedy][71]. 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."[[11]][72] While on a trip to Aachen (Germany) in 1963, von Kármán died. He was buried in Pasadena, California.[[12]][73][[13]][74] He never married. Von Kármán's fame was in the use of mathematical tools to study [fluid flow][75],[[14]][76] and the interpretation of those results to guide practical designs. He was instrumental in recognizing the importance of the [swept-back wings][77] that are ubiquitous in modern [jet aircraft][78]. ## Selected contributions[[edit][79]] Specific contributions include theories of non-elastic buckling, [unsteady wakes in circum-cylinder flow][80], stability of [laminar flow][81], [turbulence][82], [airfoils][83] in steady and unsteady flow, [boundary layers][84], and supersonic aerodynamics. He made additional contributions in other fields, including elasticity, vibration, heat transfer, and [crystallography][85]. His name also appears in a number of concepts, for example: ## Selected writings[[edit][86]] Main article: [Theodore von Kármán bibliography][87] ### Books[[edit][88]] * von Kármán, T.; [Burgers, J.
