Samuel B. Bassett, labor lawyer, died
Samuel B. Bassett, 75, of 2621 Magnolia Lane W., a prominent labor lawyer for many years, died Saturday after a long illness.
At his request there were no services. There was cremation.
A native of Washington, D.C., Mr. Bassett came here in 1920. He graduated from the University of Washington Law School in 1924. During the late 1920s he became a law partner with the late George Vanderveer, known as “counsel for the dammed,” who represented unions.
In the early 1930s, Mr. Bassett began representing the Teamsters Union and later the Retail Clerks Union. He also represented several other unions for many years.
Mr. Bassett established that unions have the right of collective bargaining as a matter of common law. He also was instrumental in many labor laws for the unions. In 1968 both labor and management and members of the judiciary honored him for his work.
Mr. Bassett was a senior partner in the firm of Bassett, Donaldson & Hafer. He was a member of the American, Washington State and Seattle-King County Bar Associations, the College Club and the Masons. He was an Army veteran of World War I.
Surviving are his wife, Virginia; a son, Stephen S. Bassett, Woodinville, two daughters, Mrs. Don Coutts, Marina Del Rey, Calif., and Mrs. Todd Smavely, Torrance, Calif., and two half sisters, Mary and Estelle Bassett, and a half brother, Harry Bassett, all of Washington, D.C.
