Passage: Engelbart was born in Portland, Oregon, on January 30, 1925, to Carl Louis Engelbart and Gladys Charlotte Amelia Munson Engelbart. His ancestors were of German, Swedish and Norwegian descent.He was the middle of three children, with a sister Dorianne (three years older), and a brother David (14 months younger). The family lived in Portland, Oregon, in his early years, and moved to the surrounding countryside along Johnson Creek when he was 8. His father died one year later. He graduated from Portland's Franklin High School in 1942.Midway through his undergraduate years at Oregon State University, near the end of World War II, he was drafted into the United States Navy, serving two years as a radar technician in the Philippines. On a small island, in a tiny hut on stilts, he read Vannevar Bush's article "As We May Think", which greatly inspired him. He returned to Oregon State and completed his bachelor's degree in electrical engineering in 1948. While at Oregon State, he was a member of Sigma Phi Epsilon social fraternity. He was hired by the National Advisory Committee for Aeronautics at the Ames Research Center, where he worked in wind tunnel maintenance. In his off hours he enjoyed hiking, camping, and folk dancing. It was there he met Ballard Fish (August 18, 1928 – June 18, 1997), who was just completing her training to become an occupational therapist. They were married in Portola State Park on May 5, 1951. Soon after, Engelbart left Ames to pursue graduate studies at the University of California, Berkeley. There, he received an M.S. in electrical engineering in 1953 and a Ph.D. in the discipline in 1955.
