Harry Fielding Reid, a professor at Case School of Applied Science in Cleveland, visited Glacier Bay in 1890 with a party of five men. The bulk of the photographs in this collection were taken in 1892 when Mr. Reid again visited Glacier Bay and continued to survey the area. Reid, a U.S. seismologist and glaciologist, received his Ph.D. from Johns Hopkins University, Baltimore in 1894 then stayed to become professor of dynamic geology from 1896 until 1930 when he was appointed emeritus professor. His early work centered on glaciers, but from 1906 he concentrated on seismology. In 1911, he developed the elastic rebound theory of earthquake mechanics, still accepted today. He was president of the Seismological Society of America in 1912 and 1913, chairman of the American Geophysical Union from 1924-1926, and a member of the National Academy of Sciences. The Seismological Society of America renamed their highest honor, the Medal, after Reid. His most lasting work was The Mechanics of the Earthquake, Volume II of the Lawson report on the 1906 earthquake, in which he made a fundamental contribution to the understanding of earthquake mechanics using observations from that earthquake, the effects of which are depicted on the medal which now bears Reid's name. Reid died in 1944 at the age of 85. His diaries and glaciological papers were donated to the American Geophysical Union.
