August Komendant

August Eduard Komendant was an Estonian and American structural engineer and a pioneer in the field of prestressed concrete, which can be used to build stronger and more graceful structures than normal concrete. He was born in Estonia and educated in engineering in Germany. After World War II he immigrated to the United States, where he wrote several books on structural engineering and served as a professor of architecture at the University of Pennsylvania.

Komendant worked with architect Louis Kahn in a productive but contentious collaboration that lasted from 1956 until Kahn's death in 1974. His innovative work as Kahn's structural engineer helped Kahn create several architecturally significant buildings, including two that won the prestigious Twenty-five Year Award given by the American Institute of Architects. He also served as structural engineer for architect Moshe Safdie on the Habitat 67 project in Montreal, Quebec, Canada.
