Name:Named in 1966 by Clifford Frondel and Jun Ito in honor of Sterling Brown Hendricks [April 13, 1902 Elysian Fields, Texas, USA - January 4, 1981 Novato, California, USA], American crystallographer, chemist, plant physiology, plant nutrition, and soil chemistry scientist. Hendricks was a pioneer in X-ray and electron diffraction technology. He was an accomplished student of the mica group and he was the first to describe the polytypes of micas. Much of his career was with the U.S. Department of Agriculture, Beltsville, Maryland, USA. He was elected to the National Academy of Sciences and was a Medal of Science winner. In 1942, Henricks climbed Mount McKinley (now Denali), Alaska as part a the 3rd expedition to do so. In 1957, he was a member of a team who went mountain climbing in Western Canada. The team was roped together of a mountain when the rope failed and the entire party fell over 80 meters. Hendricks suffered a broken shoulder and a cracked vertebra, but he went for help. Through his efforts of abandoning his own food supply to his badly injured companions and a heroic two day trek back to civilization, he saved the entire expedition. In 1958 he was in the first group of five recipients to receive the President's Award for Distinguished Civilian Service from President Dwight D. Eisenhower. Additionally, Hendricks received several awards from a variety of professional societies in recognition to the scientific advances he made.
