Theodore von Kármán (Hungarian: (szőllőskislaki) Kármán Tódor [(søːløːʃkiʃlɒki) ˈkaːrmaːn ˈtoːdor], born Tivadar Mihály Kármán, 11 May 1881 – 6 May 1963), was a Hungarian-American mathematician, aerospace engineer, and physicist who worked in aeronautics and astronautics. He was responsible for crucial advances in aerodynamics characterizing supersonic and hypersonic airflow. The human-defined threshold of outer space is named the "Kármán line" in recognition of his work. Kármán is regarded as an outstanding aerodynamic theoretician of the 20th century.[3][4][5][6]

Early life

Theodore von Kármán was born into a Jewish family in Budapest, Austria-Hungary, as Kármán Tódor, the son of Helen (Kohn, Hungarian: Kohn Ilka[7]) and Mór Kármán.[8] One of his ancestors was Rabbi Judah Loew ben Bezalel.[1] He studied engineering at the city's Royal Joseph Technical University (Budapest University of Technology and Economics). After graduating in 1902 he moved to the German Empire and joined Ludwig Prandtl at the University of Göttingen, where he received his doctorate in 1908. He taught at Göttingen for four years. In 1912 he accepted a position as director of the Aeronautical Institute at RWTH Aachen University, a leading German university. His time at RWTH Aachen was interrupted by service in the Austro-Hungarian Army from 1915 to 1918, when he designed the Petróczy-Kármán-Žurovec, an early helicopter.

After the war he returned to Aachen with his mother and sister Josephine de Karman. Some of his students took an interest in gliding and saw the competitions of the Rhön-Rossitten Gesellschaft as an opportunity to advance in aeronautics. Kármán engaged Wolfgang Klemperer to design a competitive glider.[9]

Josephine encouraged her brother Theodore to expand his science beyond national boundaries. They organized the first international conference in mechanics held in September 1922 in Innsbruck. Subsequent conferences were organized as the International Union of Theoretical and Applied Mechanics.[10] Kármán left his post at RWTH Aachen in 1930.

Apprehensive about developments in Europe regarding Nazism, in 1930 Kármán accepted the directorship of the Guggenheim Aeronautical Laboratory at the California Institute of Technology (GALCIT).[11] The directorship included provision for a research assistant, and he selected Frank Wattendorf, an American who had been studying for three years in Aachen.[12]

Another student Ernest Edwin Sechler took up the problem of making reliable airframes for aircraft, and with Kármán's support, developed an understanding of aeroelasticity.

In 1936, Kármán engaged the legal services of Andrew G. Haley to form the Aerojet Corporation, with his graduate student Frank Malina and their experimental rocketry collaborator Jack Parsons, to manufacture JATO rocket motors. He later became a naturalized citizen of the United States.

German activity during World War II increased US military interest in rocket research. In early 1943, the Experimental Engineering Division of the United States Army Air Forces Material Command forwarded to Kármán reports from British intelligence sources describing German rockets capable of travelling more than 100 miles (160 km). In a letter dated 2 August 1943 Kármán provided the Army with his analysis of and comments on the German program.[13]

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 Sint-Genesius-Rode, south of Brussels (1956).

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."[14]

Last years

The Kármán-Auditorium at the RWTH Aachen University in Germany

In June 1944, von Kármán underwent surgery for intestinal cancer in New York City. The surgery caused two hernias, and Kármán's recovery was slow. Early in September, while still in New York, he met US Army Air Forces Commanding General Henry H. Arnold on a runway at LaGuardia Airport, and Arnold then proposed that Kármán should move to Washington, D.C. to lead the Scientific Advisory Group and become a long-range planning consultant to the military. Kármán returned to Pasadena around mid-September, was appointed to the SAG position on October 23, 1944, and left Caltech in December 1944.[15]

At the age of 81 Kármán 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."[16]

Kármán never married. He died on a trip to Aachen, West Germany, in 1963, five days short of his 82nd birthday,[17] and his body was returned to the United States to be entombed in the Beth Olam Mausoleum at what is now the Hollywood Forever Cemetery.[18] He has sometimes been described as one of The Martians.[19]

Kármán's fame was in the use of mathematical tools to study fluid flow,[20] and the interpretation of those results to guide practical designs. He was instrumental in recognizing the importance of swept-back wings 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:

Autobiography

Four years after Kármán died his autobiography The Wind and Beyond was published by Lee Edson with Little, Brown and Company. Seven major academic journals then followed with book reviews by noted authors: As the book was non-technical, written for the general reader, Thomas P. Hughes[21] cited that as problematic given the technical context of Kármán's work. Hughes conceded that Kármán "exhibited a genius for finding the simplifying assumptions that made possible the mathematical analysis." While acknowledging Kármán's gifts as an applied mathematician and teacher, Stanley Corrsin points out that the autobiography is "marriage between a man and his ego." In the later part of his life, Kármán was a "planner of global symposia and societies" and a "consultant to the upper echelons of the Pentagon corps."[22]

On creativity, Kármán wrote "the finest creative thought comes not out of organized teams but out of the quiet of one's own world."[9]: 307  In his review[23] I. B. Holley noted "penetrating insights into the creative process, its ingredients, nurture and exploitation." According to Holley, Kármán was given to "convivial drinking and the company of beautiful women."

An enthusiastic review by J. Kestin[24] advised readers to buy and study the book, and prize it as a reference. On the other hand, Charles Süsskind[25] faults Kármán for his contempt for the conventional (gaminarie). Süsskind expected the book to show some reaction to Wernher von Braun's coming to America, and some clarification of the Hsue-shen Tsien affair, rather than "lapses into generalities". Süsskind also tags Kármán as a militarist: a "forthright engineer who is quite unabashed about his lifelong association with military authorities in whatever country he happened to reside at the time."

Sydney Goldstein, who also wrote the Royal Society memoir for Kármán, reviewed the autobiography[26] and remembered "an eminent engineer and scientist, warm-hearted and witty, much traveled, well-known by many, devoted to international collaboration, who, in his own words, as a scientist found the military 'the most comfortable group to deal with'".
