The Woodruff Papers contain: correspondence; datebooks (1916-1958); professional notes, drawings and plans pertaining to Woodruff's lengthy career as an electrical engineer in San Joaquin County (1920-1968). They also contain: Mr. and Mrs. Woodruff's school notes; early financial records (1912-17); gardening records (1950s); and, miscellaneous biographical materials.

Electrical engineer, Ennis Casselberry Woodruff (1894-1977), graduated from the University of California (1916), taught aviation at the same institution during World War I, and was then employed by Pacific Gas and Electric in the San Joaquin County region for nearly forty years (1920-1959). He also taught a safety course at the University during World War II (1943). While employed by PG & E, and, especially after his retirement, Woodruff served as an electrical consultant to: the College of the Pacific (1947-62); the Stockton Unified School District (1932-1957); various commercial enterprises in Stockton---most notably the Lincoln Village Shoping Center (1961-67); and, some lumber companies in the Eureka area (1950s). Woodruff was also involved in Stockton community affairs, notably with the Boy Scouts, for whom he established the first local Explorer Troop. His hobby was flower gardening, work which he approached (and documented) with the same meticulous thoroughness he applied to engineering activities.
