Robert Roy Coats (1910–1995) was born in Toronto, Canada, and grew up in Marshalltown, Iowa and Seattle, Washington. He graduated valedictorian of his high school class in Seattle at the age of 16, and attended the University of Washington, where he received both a B.S. and M.S. degree in Geology and Mining (1931 and 1932). He continued graduate work at the University of California at Berkeley, receiving his doctorate in 1938, with a thesis on the ore bodies of the Virginia City mining district in Nevada. He was known as an eccentric and brilliant student. In 1937, Coats took a teaching job at the University of Alaska at Fairbanks. He left that job for a post with the U.S. Geological Survey in 1939, in Washington, D.C. As part of the Alaska Branch of the USGS, he continued working in Alaska, mapping in the Chichagof, Anikovik, Nome, Solomon, Kigluaik and Kobuk River areas, among others.
