Albert A. Bühlmann

• Professor Albert A. Bühlmann (16 May 1923 – 16 March 1994) was a Swiss physician who was principally responsible for a number of important contributions to decompression science at the Laboratory of Hyperbaric Physiology at the University Hospital in Zürich, Switzerland.[1][2
  
• His impact on diving ranged from complex commercial and military diving to the occasional recreational diver.[1
  
• In 1959, Hannes Keller became interested in deep diving and developed tables for mixed-gas decompression. Not a diver himself, Bühlmann was intrigued by project and suggested suitable breathing gases.[2][7] Keller successfully tested his idea in the Lake Zurich where he reached a depth of 400 feet and then Lake Maggiore where he reached a depth of 728 feet.
