Other former staff were hanged for war crimes in the Dachau Trials and the Belsen Trial, including camp leaders Josef Kramer, Franz Hössler, and Vinzenz Schöttl; doctor Friedrich Entress; and guards Irma Grese and Elisabeth Volkenrath. The Frankfurt Auschwitz trials, held in West Germany from 20 December 1963 to 20 August 1965, convicted 17 of 22 defendants, giving them prison sentences ranging from life to three years and three months. Bruno Tesch and Karl Weinbacher, the owner and the chief executive officer of the firm Tesch & Stabenow, one of the suppliers of Zyklon B, were executed for knowingly supplying the chemical for use on humans.
Dynatron was Schindler's elevator drive system launched in 1965. It is based on Schlieren's Monotron drive which was developed in 1958. These drive systems are particularly distinguished by direct stopping, regulated electronically as a function of the distance to the floor level. Dynatron should not be confused with Schindler's Dynator (Ward Leonard) drive, which was introduced in 1945.
In 1951, Poldek Pfefferberg approached director Fritz Lang and asked him to consider making a film about Schindler. Also on Pfefferberg's initiative, in 1964 Schindler received a $20,000 advance from MGM for a proposed film treatment titled To the Last Hour. Neither film was ever made, and Schindler quickly spent the money he received from MGM. He was also approached in the 1960s by MCA of Germany and Walt Disney Productions in Vienna, but again nothing came of these projects.
