Robert William Hamilton Jr. (1930 – 16 September 2011), known asBill, was an Americanphysiologist known for his work inhyperbaricphysiology.

He was predeceased by his first wife Beverly, son Beto and daughter Kitty.

He was survived by his wife Kathryn (née Faulkner) of nearly 40 years, daughters Lucy and Sally, grandsons, Felix, Bobby, Zach, Tyler and Truman.^[1]

He earned his degree in liberal arts at theUniversity of Texas, followed by a master's degree in animalreproductive biology atTexas A&M.

He earned his Doctoral degree in physiology andbiophysics in 1964 from theUniversity of Minnesota.^[1]

Hamilton served as afighter pilot in theU.S. Air Force in theKorean War andVietnam, earning the rank ofmajor. He was also awarded theDistinguished Flying Cross,Air Medal, and other decorations.^{[citation needed]}

He helped solve equipment problems on unsuccessful bailouts as a Life Support Officer, which earned him aNational Academy of Sciences recommendation toNASA as a ScientistAstronaut.^[1]

Hamilton left the Air Force with and moved toBuffalo, New York, in 1964, where he met Heinz Schreiner and began his work on the undersea world as a scientist and director of the Ocean Systems environmental physiology and diving research lab inTarrytown, New York.^[1]

Hamilton investigated the effects of gases in hyperbaric andhypobaric environments which led to the development ofdecompression modelling tools and operational procedures for divers, astronauts, hyperbaric chambers, and tunnel andcaisson workers. He was both the physiologist and test subject on the first manned laboratorysaturation diving to the continental shelf pressure of 12 ATA (200 msw) in 1965.

He founded Hamilton Research, Ltd. (1976), for decompression and hyperbaric research, which developed procedures and techniques to mitigate the effects ofHigh Pressure Neurological Syndrome, and the Diving Computational Analysis Program (DCAP), which he co-developed with David J. Kenyon.

Hamilton was the principal investigator of the NOAA Repex Oxygen Exposure tables to assist divers in avoidingoxygen toxicity. These became the basis for most oxygen exposure calculation methods used for saturation andrepetitive diving exposures to oxygen in breathing mixtures.

In the late 1980s, he developed project-specific customdecompression tables. His work with decompression tables, physiological effects of gases, and methods of managing exposure to oxygen, helped to open up the new field oftechnical diving.^[1] This included work with theNational Oceanographic and Atmospheric Administration (NOAA) developing "Monitor Mix" breathing gas for dives to the USSMonitor. This breathing gas became NOAATrimix I, with decompression tables designed by Bill Hamilton published in the NOAA Diving Manual.^[2]
