Thomas Baker "Tom" Slick, Jr. (May 6, 1916 – October 6, 1962) was a San Antonio, Texas-based inventor, businessman, adventurer, and heir to an oil business. Slick's father, Thomas Baker Slick, Sr., a.k.a. "The King of the Wildcatters", had made a fortune during the Oklahoma oil boom of the 1910s. He was notable for discovering Oklahoma's then-largest oil field, the Cushing Oil Field.
During the 1950s, Slick was an adventurer. He turned his attention to expeditions to investigate the Loch Ness Monster, the Yeti, Bigfoot and the Trinity Alps giant salamander. Slick's interest in cryptozoology was little known until the 1989 publication of the biography Tom Slick and the Search for Yeti, by Loren Coleman. Coleman continued his study of Tom Slick in 2002 with Tom Slick: True Life Encounters in Cryptozoology. That book mentions many of Tom Slick's adventures, in politics, art, science, and cryptozoology, including his involvement with the CIA and Howard Hughes.
Tom Slick was a friend of many celebrities, including Hughes and fellow flier Jimmy Stewart. Stewart, for example, assisted a Slick-backed expedition in smuggling a piece of the Pangboche Yeti hand back to England for scientific analysis, Loren Coleman was to discover from Slick's files and confirmation from Stewart before his death.
Slick founded several research organizations, beginning with the forerunner of the Texas Biomedical Research Institute in 1941. His most well-known legacy is the non-profit Southwest Research Institute (SwRI), which he founded in 1947 to seek revolutionary advancements in technology. SwRI continues to advance pure and applied science in a variety of fields from lubricant and motor fuel formulation to solar physics and planetary science. He also founded the Mind Science Foundation in San Antonio in 1958 to do consciousness research.
