MERRILL, GEORGE PERKINS
(b. Auburn. Maine, 31 May 1854; d. Auburn, 15 August 1929)
Merrill was a descendant of Nathaniel Merrill, who had settled in the Massachusetts Bay Colony in the 1630’s His father, Lucius Merrill, was a carpenter and cabinetmaker. His mother, Anne Elizabeth Jones, was the daughter of the Reverend Elijah Jones of Minot, Maine, whose scholarship had a profound influence upon the intellectual life of his grandson. One of seven children, Merrill began to earn his own living at an early age, finding employment as a farmhand and in shoe factories. He was twenty-two years old when he entered the Maine State College of Agriculture and the Mechanic Arts (now the University of Maine), where he majored in chemistry and graduated with a B.Sc. degree in 1879. He then became a laboratory assistant, working on the chemistry of foods, at Wesleyan University, Middletown, Connecticut. There he became acquainted with G. Brown Goode, formerly curator of Wesleyan’s museum collections and at that time in charge of the U.S. National Museum in the Smithsonian Institution and director of the survey of fisheries for the tenth census. Goode appointed Merrill to the census staff in 1880 and to the Museum staff in 1881 as aid to George W. Hawes, who had just become curator of the geological collections. After Hawes’s death in 1882, Merrill was put in charge of petrology and physical geology; and in 1897 he became head curator of the department of geology in the U.S. National Museum, a position that he held until his death. He also served as part-time professor of geology and mineralogy at Columbian College (renamed George Washington University in 1904) from 1893 to 1915.
Merrill was married in 1883 to Sarah Farington, of Portland, Maine. She died in 1894, leaving one son and three daughters. He was married again in 1900 to Katherine L. Vancey of Virginia, by whom he had one daughter. He was of sturdy build, alert and active, accustomed to long hours in office and laboratory; an avid reader, he was fond of poetry and music. Austere and reserved on first acquaintance, to his many friends Merrill displayed a warm and generous heart. He was a member of the National Academy of Sciences; the American Philosophical Society; the Geological Society of America, of which he was vice-president in 1920; the Washington, the Maryland, and the Philadelphia academies of science; and the Geological Society of Washington, of which he was president in 1906–1907; and a corresponding member of the American Institute of Architects.
Merrill made scientific contributions in at least five distinct areas. As a museum administrator he built up the department of geology in the U.S. National Museum and made it one of the world’s greatest and best-organized geological collections. Introduced by Hawes to the new petrologic technique of microscopic study of thin sections of rocks, he applied that procedure to the large collection of building stones assembled in connection with the tenth census and enlarged in succeeding years. This not only led to the publication of his most widely read book, Stones for Building and Decoration, but also established such a reputation for him that he was influential in the selection of stones for many governmental buildings, most notably the Lincoln Memorial. These studies naturally turned Merrill’s attention to the processes of rock weathering. Here his early training in chemistry proved valuable and his Treatise on Rocks, Rock Weathering, and Soils was immediately hailed by European as well as American geologists, and led to his recognition in agricultural circles as the outstanding authority of his time on soils and their origin.
A fourth area in which Merrill’s scientific contributions were especially notable involved the study of meteorites. He was one of the first to “regard the meteorites as world matter”; and in 1906 he correctly identified Coon Butte, near Canyon Diablo, Arizona (now known as Meteor Crater), as an impact crater. Last among his areas of accomplishment was that of the history of geological science; his three works on this subject (1906, 1920, 1924) are indispensable source material
Among Merrill’s many honors were an honorary Ph.D. from what is now the University of Maine, in 1889, the Sc.D. from George Washington University in 1917, and the J. L. Smith gold medal of the National Academy of Sciences in 1922.
