Career as Professor of History, Dean, AHA member and President
Stephens immigrated to the United States in 1894 and took the position of Professor at Cornell University in the Department of History, where he taught European History. At Cornell, Stephens took a particular interest in advising undergraduates, starting two traditions which endured at Cornell for the next two decades: Thursday nights for upper classmen, and career conferences and advice to seniors as to their future professional careers. He was also an avid fundraiser for Cornell's athletic teams. In 1902, Stephens went to the University of California as Professor of History and Director of University Extension, a position he held from 1902–1909. He served as Dean of the University of California College of Arts and Sciences from the fall of 1918 until his death. During his time at Berkeley, he worked to build the Bancroft Library's collection of historical materials, with special success in the area of Spanish and Mexican History, now known as the Bolton Collection. Stephens was involved with the Bohemian Club and wrote the script for St. Patrick at Tara, the main Grove Play performed in 1909 at the Bohemian Grove. The play depicted Saint Patrick and his interaction with druids, chieftains and kings of Ireland. Stephens was an active member of the American Historical Association serving as its President in 1915. His most notable contribution in the AHA, however, was as a member of the Committee of Seven, which in 1899 produced the report The Study of History in Schools for the AHA, and which influenced the teaching of history in American schools for the next 40 years. Stephens Hall on the U.C. Berkeley campus is named for him, as was the Lodge of Free and Accepted Masons, chartered by the Grand Lodge of F. & A. Masons of California and Hawaii: Henry Morse Stephens #541, for which membership was open only to UC administrators, alumni, faculty and students. The lodge merged with other Berkeley, CA Lodges and is now part of Bay Cities Lodge #337, now in Richmond.
After the 1906 San Francisco earthquake, at the suggestion University of California President Benjamin Ide Wheeler, Morse joined the Committee of 50, and in consultation with Governor Pardee, moved to the Earthquake History and Statistics Committee. As a member of this committee, he worked until his death to gather as many accounts and as much historical material as he could that was related to the earthquake. Morse collected over 800 individual accounts of the earthquake and fire as well as numerous newspaper articles, photographs, and other archival material. Unfortunately, after his death, the archive was never incorporated into the Bancroft library collection, as he had intended, and was lost in the 1920s, perhaps in a 1923 Berkeley fire. When World War I broke out, Stephens began actively soliciting materials from around the world to document and formed a "Great War History Committee," work that was cut short by his death on April 16, 1919.
