Walter Franz

From Wikipedia, the free encyclopedia

Walter Franz (1911 – 1992) was a theoretical physicist who independently discovered the Franz-Keldysh effect.

Franz was a student of Arnold Sommerfeld at the University of Munich. He was granted his Ph.D. in 1934.^{[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 Hauygens’ principle.^[3]

With Adolf Kratzer, another student of Sommerfeld, Franz co-authored the book Transzendente Funktionen.^[4] An academic descendent of Franz, Ludwig Tewordt, is cited as having received his Ph.D. at the Westfälische Wilhelms-Universität Münster, in 1953.^[5] The article in which Franz independently published the Franz-Keldysh effect was published in 1958.^[6]
