Erhard Glatzel

from Wikipedia, the free encyclopedia

Erhard Friedrich Glatzel (born October 25, 1925 in Marl ; † February 4, 2002 in Heidenheim ) was a German optician.

Life

Glatzel studied mathematics at the University of Bonn and in 1952 completed his dissertation at the Krupp company as an external doctoral student at the University of Cologne. He then began working for Zeiss in Oberkochen in October 1954 , where he was promoted to head of the lens design department and stayed with the company until he retired in March 1989. He designed a variety of lenses, but became known for his camera lenses. He played a leading role in the development of the Hologon , Distagon , Biogon , Medion , Tessar , Sonnar and Planar . For his Biogon 60 mm ƒ / 5.6 wide-angle lens, specially designed for the Hasselblad camera of the moon mission, he was awarded The Apollo Achievement Award by NASA . His Planar 50mm f / 0.7 is considered to be the fastest lens in the world and was used by Stanley Kubrick for the film Barry Lyndon , among others . In 1977, Zeiss received an Oscar for the company's camera lenses, including Glatzel's Distagon ƒ / 1.2.

Glatzel published specialist articles and was one of the first to use the supercomputers of the time to calculate lenses. Among other things, he developed the adaptive optimization method for lens construction.
