Thomas C. Buchanan was a descendant of a pioneer Beaver
County family that moved in the middle of the 19th century from
the Southside to Beaver, where his father was a prominent attorney
and business man. After graduation from Washington and Jefferson
College and the University of Pittsburgh Law School, and Army
service during World War 1, he began to practice law in Beaver.
Active in Democratic politics, he was appointed Secretary of Forest
and Waters by Governor Earle in 1935, and subsequently served
both the Public Service and Public Utilities Commissions. Within
several years after returning to private practice in 1945 he was
appointed by President Truman to the Federal Power Commission,
remaining in this post until 1953, when he returned again to Beaver
and practiced law until his death in 1958.
