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. His impact on diving ranged from complex commercial and military diving to the occasional recreational diver. He is held in high regard for his professional ethics and attention to his research subjects.
After completing his education at the University of Zürich, Bühlmann specialized in pathophysiology of the respiratory and circulatory systems. He was particularly interested in respiratory physiology at high altitudes and high pressure environments.
The Bühlmann decompression algorithm is used to create decompression tables.
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. 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.
Building off the previous work of John Scott Haldane and Robert Workman, and working off funding from Shell Oil Company, Bühlmann designed studies to establish the longest half-times of nitrogen and helium. These studies were confirmed by the Capshell experiments in the Mediterranean sea in 1966.
