Franz Staeble

from Wikipedia, the free encyclopedia

Franz Staeble (* 1876 ; † 1950 ) was a German physicist (optician) and entrepreneur in the photographic industry.

Stäble in 1901 at the Ludwig Maximilian University of Munich with a thesis on the study of surfaces whose curvature lines at orthogonal projection onto another surface again curvature lines doctorate . The speaker was Carl Louis Lindemann , co- speaker Gustav A. Bauer . Together with Erwin Lihotzky , Staeble continued his ideas from 1907 on the optical analysis of spherically uncorrected optical systems. These considerations led to the formulation of today's Staeble-Lihotzky condition in 1919 .

Franz Staeble founded the Staeble factory, which was relocated to Schongau in 1944, in Munich together with Alfred Neumann and O. Jaeger on May 5, 1908 . Together with his co-partner A. Neumann, he published the photographic lens. Its assessment and utilization , the third improved edition of which had to be published in 1924.
