HISTORICAL NOTE

George P. Merrill (1854-1929) graduated from the University of Maine in 1879 with a B.S. degree in chemistry and then accepted a teaching position at Wesleyan University. There he became acquainted with George Brown Goode, who helped curate Wesleyan's museum collections in addition to administering the United States National Museum (USNM). Later, Merrill earned his M.S., 1883, and Ph.D., 1889, degrees from the University of Maine. In 1917 he received an honorary Sc.D. degree from The George Washington University where he was professor of Mineralogy and Geology from 1893 to 1916.

In the winter of 1880-1881 Merrill was appointed aide at the United States Bureau of Fisheries. In July 1881 he transferred to the USNM where he was employed as an aide in the Department of Mineralogy. The following year he was promoted to assistant in the Department's Section of Building Stones. Subsequently, he held positions as acting curator, Department of Lithology and Physical Geology, 1883-1885; curator, Department of Lithology and Physical Geology, 1886- 1890; curator, Department of Geology, 1890-1916; curator, Division of Physical and Chemical Geology (Systematics and Applied), 1898-1929; and head curator, Department of Geology, 1917-1929.

Merrill pioneered in the study of using stone for building purposes and in the study of the process of rock weathering. Later, he applied petrology to the study of meteorites.

In addition to his scientific work, Merrill was a historian of North American geology. In connection with his two works on the history of American geology, "Contributions to the History of American Geology" (Report of the United States National Museum for 1904, pp. 189-733) and The First One Hundred Years of American Geology (1924), Merrill assembled a collection of photographs and correspondence, with many of the photographs and portraits appearing in this collection.
