Revision as of 00:29, 29 February 2012

Son of Ernst Leitz II, he was know as Ludwig Leitz II (1907–1992) named after his father's elder brother Ludwig Leitz I ( who had passed away in 1898). Ludwig II was the designer (with Wilhelm Stein) of the rangefinder for the M3. Along with his brothers, Ernst III (1906-1979) and Günther (1914-1969), Ludwig was co-owner of Leitz from 1956 to 1974.

"Von der Konstruktionsseite für die Leica M3 sind zu nennen: Dr. Ludwig Leitz, LTG.gesammt, "Willi" Wilhelm Stein, Ltg. Konstruktion und Adolf Groß, Ltg. Formgestaltung sowie Prof. Scheuernstuhl als Bildhauer und sein Meisterschüler Heinrich Janke aus Hannover, der spätere Leiter dieser Abteilung. Später bestand das Team aus Hans-Kurt Uellenberg, H. Janke, Ernst Rühl und Bernd Nickel (von links, siehe Abb.!). Hier 3 Entwürfe für die Leica M3 aus den 50èr und 60èr Jahren. 1953, 1956, 1957 und 1961. Heute nennt man das Design oder CAD bei Leica. Eine leider früher und auch heute viel zu gering geachtete Species für neue Produkte und ihren Erfolg. Damals hats aber geklappt Grüße Hendrik"
