1991 - Albert A. Buehlmann

Hyperbaric physician

Bhlmann fotoBühlmann Albert (1923 – 1994)

He 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. He is the inventor of the Bühlmann decompression algorithm used to create decompression  tables.

He perfected the theory of mixed gases that in 1959, Hannes Keller (Golden Trident 1961) successfully tested in the  Zurich lake where he reached in November 1959 a depth of 400 feet and the following year in Californa 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 of nitrogen and helium. These studies were confirmed by the Capshell experiments in the Mediterranean sea in 1966. The results of Bühlmann's research, in cooperation with Dr. Max Hahn that began in 1959, were published in a 1983 German book entitled Decompression-Decompression Sickness, considered the  most complete paper on decompression sickness. In 1987 developed the SAA Bühlmann System that is the base for the decompression time calculations for no-decompression dives adopted by the larger part of diving computers. Bühlmann recognized the problems associated with altitude diving and developed  decompression tables successfully tested in 1987 in the Lake Titicaca at 3800 meters above sea level
