Karl Deutsch
Karl Wolfgang Deutsch (21 July 1912 – 1 November 1992) was a Czech social and political scientist. He was a professor at MIT, Yale University and Harvard University, as well as Director of WZB Berlin Social Science Center.

Deutsch studied war and peace, nationalism, co-operation, and communication, as well as pioneered quantitative methods and formal system analysis and model-thinking into the field of political and social sciences, contributing to the development of sociological liberalism school in international relations.

Early life
Born into a German-speaking Jewish family in Prague on 21 July 1912 when the city was part of the Austro-Hungarian Empire, Deutsch became a citizen of Czechoslovakia after World War I. His mother Maria was a Social Democrat, and one of the first women to be elected to the Czechoslovak parliament in 1920. His father Martin Moritz Deutsch owned an optical shop on Prague's Wenceslas Square and was also active in the Czechoslovak Social Democratic Worker's Party. His uncle Julius Deutsch was an important political leader in the Social Democratic Party of Austria.

Education
Karl studied law at the German University of Prague, where he graduated in 1934. He discontinued further studies as his overt anti-Nazi stance caused opposition by pro-Nazi students. Karl married his wife Ruth Slonitz in 1936, and after spending two years in England returned to Prague where due to his former anti-Nazi activities, he could not return to the German University. He instead joined its Czech counterpart, the Charles University, where he obtained a law degree in international and canon law and a PhD in Political Sciences in 1938.

Emigration and career
In 1938 following the Munich Agreement allowing German troops to enter the Sudetenland, he and his wife did not return from a trip to the United States. In 1939 Deutsch obtained a scholarship to carry out advanced studies at Harvard University where he received a second PhD in political science in 1951. His dissertation, Nationalism and Social Communication, was awarded Harvard’s Sumner Prize in 1951.

During World War II he worked for the Office of Strategic Services and participated in the San Francisco conference that resulted in the creation of the United Nations in 1945. Deutsch taught at several universities; first at MIT from 1943 to 1956 (he became a professor of history and political science at MIT in 1952); then at Yale University (initially as a visiting professor in 1957 before becoming a permanent professor in 1958) until 1967; and again at Harvard until 1982. He became a professor at Harvard in 1967, becoming Stanfield Professor of International Peace at Harvard in 1971, a position he held until his death. At Yale University, Deutsch developed the Yale Political Data Program, which collected quantitative indicators for theory testing.

Deutsch worked extensively on cybernetics, on the application of simulation and system dynamics models to the study of social, political, and economic problems, known as wicked problems. He built upon earlier efforts at world modeling such as those advanced and advocated by authors of the Club of Rome such as Limits to Growth by Donella Meadows, et al. (1972). He introduced new concepts such as security community to the literature.

He held several other prestigious positions; he was a member of the board of World Society Foundation in Zürich, Switzerland from 1984 onwards. He was also elected President of the American Political Science Association in 1969, of the International Political Science Association in 1976, and of the Society for General Systems Research in 1983. From 1977 to 1987, he was Director of the Social Science Research Center Berlin (Wissenschaftszentrum Berlin für Sozialforschung, WZB) in Berlin.

Karl W. Deutsch in his book The Nerves of Government: Models of Political Communication and Control hypothesized about “information elites, controlling means of mass communication and, accordingly, power institutions, the functioning of which is based on the use of information in their activities.”

Personal life
He died in Cambridge, Massachusetts, on 1 November 1992. He has two daughters, and three grandchildren.
