Biography

Personal life and education

Purcell was born in North Bend, Nebraska, one of two children of John and Mary Gillis Purcell. His father died when he was 3, and as he grew up, Purcell developed a fascination with bridges. He was educated in civil engineering at Stanford University (for one semester) and at the University of Nebraska–Lincoln where he specialized in bridge design. He married Minnie Pullen in 1914, the daughter of a Portland, Oregon farmer. They had no children. he worked at a variety of jobs in ten different locations. His first full-time position was with the Union Pacific Railroad, during which he built a steel girder span in Wyoming, his first bridge. He then went to Peru for two years as an engineer for mines in the Cerro de Pasco area. He returned to the United States as chief engineer for a logging railroad in Oregon. He then supervised the construction of bridges and highways in several states, mostly in the Pacific Northwest. During his tenure, he supervised bridge projects along the Historic Columbia River Highway and a number of smaller bridges throughout the state. He established Oregon's first statewide bridge design department. After he left employment with the state of Oregon in 1918, he became a District Engineer for U.S. Bureau of Public Roads.

Professional accomplishments

Built San Francisco–Oakland Bay Bridge

In 1928, Purcell was appointed by Governor C. C. Young as the California State Highway Engineer. In 1929, he was appointed technical adviser to the 1929 Hoover-Young San Francisco-Oakland Bay Bridge Commission, which commissioned construction of the -long San Francisco–Oakland Bay Bridge. When the commission finished its work, Purcell was appointed by Governor Jim Rolph as the Chief Engineer responsible for the design and construction of the bridge. During construction, the project was held up by the maritime strikes of 1934. Despite these and many other challenges, the bridge was completed several months ahead of schedule. The western portion of the bridge relied on a central -tall anchorage, of which is beneath the surface of the water. It is the world's largest pier. He was buried at East Lawn Memorial Park.
