Walter Franz
From Wikipedia, the free encyclopedia
Walter Franz (8 April 1911, in Munich – 16 February 1992, in Münster) was a German theoretical physicist who independently discovered the Franz–Keldysh effect.
Franz was a student of Arnold Sommerfeld at the Ludwig-Maximilians-Universität München (LMU) in Germany. There he was granted the doctoral degree Dr.phil. in 1934. The (German) title of his dissertation was Comptoneffekt am gebundenen Elektron.[1][2] In the preface to the book Optik, Sommerfeld cited him for "the most recent and particularly lucid treatment" of the vectorial generalization of Huygens’ principle.[3]
With Adolf Kratzer, another student of Sommerfeld, Franz co-authored the book Transzendente Funktionen. The article in which Franz independently published the Franz–Keldysh effect was published in 1958.
