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.
