Ludwig Bertele

Ludwig Bertele (born December 25, 1900 in Munich , † November 16, 1985 in Wildhaus SG ) was a German optics designer. From 1916 he was trained in calculating optical systems at Rodenstock . From 1919 he worked for the Dresdner Ernemann-Werke , which was merged into Zeiss Ikon in 1926 . From 1946 to 1956 he invented and calculated innovative aerial photography lenses for the Swiss company Wild Heerbrugg . In 1958, ETH Zurich awarded him an honorary doctorate for his achievements . From 1956 to 1973 he was a freelancer at Wild Heerbrugg AG.

Important photographic lenses developed by him in the lead include:

  • Ernostar (1923)
  • Sonnar (around 1930)
  • Biogon (1935)
  • Aerial lens Aviotar (1948)
  • Super wide-angle biogon with 90 ° field of view (1951)
  • Aviogon aerial photo lens with 90 ° field of view (1952)
  • Aerial lens Super-Aviogon with 120 ° angle of view

Bertele's developments were groundbreaking for the optical industry at the time. The Biogon was conducted at Hasselblad cameras of NASA used the Gemini flights (1965-66) and the later Apollo missions to document (1968-1972).

In 1980 Bertele was awarded the Culture Prize of the German Society for Photography . In 1958 the ETH Zurich awarded Ludwig J. Bertele an honorary doctorate.
