Name:
Named in 1988 by Pete J. Dunn, Donald Ralph Peacor, Alan J. Criddle, and Chris J. Stanley in honor of Fred Earl Ingerson [October 28, 1906, in Barstow, Texas, USA - June 11, 1993 Austin, Texas, USA], geochemist of the Geophysical Laboratory of the Carnegie Institution (1935-1947), Chief Geochemist at the Petrology Branch of the United States Geological Survey (1947-1958), and professor of geology at the University of Texas in Austin (1958-1977). His research specialty included fluid inclusion studies, characterization of ore-forming fluids, geothermometry, and petrofabric analysis. "Many honors and accomplishments typify Ingerson’s outstanding career: Honorary Doctor of Science (Hardin-Simmons College, 1942), Day Medal (Geological Society of America, 1955), Distinguished Service Award (U.S. Department of the Interior, 1959), and the Distinguished Alumnus Award (Hardin-Simmons University, 1977). Ingerson was the founder of two major societies and their journals — The Geochemical Society and its publication, Geochimica et Cosmochimica Acta, and the International Association of Geochemistry and Cosmochemistry and its journal Organic Geochemistry. In recognition of the important role he played in establishing these organizations, Earl Ingerson was asked to serve as the first president of each. He held membership, fellowship, and committee service in more than 35 professional societies in 13 nations." (Internet biography, Jackson School of Geosciences, Austin, Texas).
