Biographical Note
Erwin Loewy was born in Pilsen, Czechoslovakia (now Czech Republic) on September 18, 1897. He and his brother Ludwig worked for a German shipbuilding firm (Schloemann), designing and managing, until the rise of the Nazi state.  He escaped from Germany in 1935, and from France in 1940.  He came to the United States and worked diligently to influence the Armed Forces and industry to accept the need for large extrusion presses to form airplane parts, as had already been developed in Europe. After World War II, he helped relocate some large presses from Europe. He and his company continued to develop extremely large presses for civilian use in the United States.  Erwin Loewy died July 13, 1959.

The Loewy Family Foundation selected Lehigh University to carry on the excellence that the brothers had exhibited, and established the Loewy Chair (1992) and the Loewy Visiting Professorship (1999) in Materials Forming and Processing.
