Egon Eiermann (born September 29, 1904, Neuendorf; died July 20, 1970, Baden-Baden) was one of Germany's most prominent architects in the second half of the 20th century.
Eiermann studied at the Technical University of Berlin. He worked for the Karstadt building department for a time, and before World War II had an office with fellow architect Fritz Jaenecke. He joined the faculty of the university in Karlsruhe in 1947, working there on developing steel frame construction methods.
A functionalist, his major works include: the textile mill at Blumberg (1951); the West German pavilion at the Brussels World Exhibition (with Sep Ruf, 1958); the West German embassy in Washington, D.C. (1958-1964); a building for the German Parliament (Bundestag) in Bonn (1965-1969); the IBM-Germany Headquarters in Stuttgart (1967-1972); and, the Olivetti building in Frankfurt (1968-1972). By far his most famous work is the new church on the site of the Kaiser Wilhelm Memorial Church in Berlin (1959-1963).
