Diver, Marine Biologist

Conrad Limbaugh began skin diving as a teenager along the rocky coasts of Southern California. During the summer of 1948, he studied marine invertebrates and ichthyology at Stanford's Hopkins Marine Station in Pacific Grove, California. He received a Bachelor of Arts degree in Biology from Whittier College in 1949. Limbaugh transferred to Scripps Institution of Oceanography in 1950, where he began studies under Dr. Carl Hubbs. At Scripps he began to combine scuba diving with scientific research more directly. He was appointed the first diving officer at Scripps. During the mid-1950s, Limbaugh began to travel to collect specimens and study the marine environment. Among the more notable expeditions in which he participated were two Scripps expeditions to Clipperton Island in 1956 and 1958 (the latter of which he led), several to Guadalupe Island, Mexico, and at least two to Cabo San Lucas, Mexico. Limbaugh also did a substantial amount of work under contract with the United States Navy. His most significant contribution in biology was his work on cleaning symbiosis. Limbaugh lost his life at the age of 35 on March 20, 1960, when he lost his way in the labyrinth that was the underground river at Port Miou, near Cassis, 20 miles from Marseille, France. A number of marine species have been named for Limbaugh, including Chromis limbaughi, Holocanthus limbaughi, Elacanthus limbaughi, Chaenopsis limbaughi, and Cadlina Limbaughorum.
