Paul Rudolph (* Nov. 14th 1858 in Kahla, Thuringia; † March 8th 1935 in Nuremberg) was a German scientist and optician. He was an employee of Carl Zeiss when he created the first anastigmatic lens which was introduced in 1889 as the Zeiss Anastigmat (later sold as the Protar). Rudolph also developed the Planar, a lens with near-flat focal plane, and the most-copied popular advanced still camera lens design Tessar. He retired early but was forced to re-enter business after losing his capital through inflation. In 1920 he was hired by Meyer where he finished his development of the highly color-corrected Plasmat lens which had a higher correction of spherical aberration than Goerz' famous Dagor. It was introduced as a convertible lens with lens speed 1:4.5; the cine lens versions like the Kino Plasmat 1:1,5/16 were the fastest lenses of the mid-1920s.
