Why Is Wolfgang Knauss Influential?

(Suggest an Edit or Addition)

According to Wikipedia, Wolfgang Gustav Knauss is an American engineer. He was Theodore von Kármán Professor of Aeronautics and Applied Mechanics at Caltech . Education Knauss grew up in Siegen during the Second World War as the son of a Methodist pastor. In 1954 he made his Abitur at the Helmholtz Realgymnasium in Heidelberg. After the war, the acquaintance of a Methodist pastor from Pasadena , who visited the family in Heidelberg, enabled Knauss to attend Pasadena City College and study at Caltech from 1955 with a bachelor's degree in 1958. Originally, he wanted to study rocket technology, but ended up studying fracture mechanics with aeronautics professor Max L. Williams. He earned his master's degree in 1959 and received his doctorate in 1963.
