Pfeifle was born on April 14, 1880, on a farm in
Almont, Pennsylvania (a former crossroads village in what was then farm country, near
Sellersville). His parents were Franklin (Frank) and Catherine (Headman) Pfeifle, of
Pennsylvania Dutch ancestry. The family moved in the 1880s, and Bob's primary-school education was at
Lansdale. The family moved to Philadelphia when Pfeifle was 12 years old. He served his apprenticeship as a
blacksmith there in the 1890s. He did not like the blacksmith trade, but because his father insisted, he finished the apprenticeship; afterward, from 1899, he left that trade and took up the one he preferred,
carpentry, in which he remained for decades afterward. As a young man he took up the harmonica, tap dancing, and amateur theatre. McQuade and Orpe said, "He took up
boxing, and became a competent amateur, but gave up the ring, he said later, after he got "clobbered." ==Career==
