Barringer was the son of Rufus Barringer and was named after his grandfather, General Paul Barringer (1776-1835). He spent some of his childhood in Concord, North Carolina, where, as an eight-year-old, he beat Confederate States of America President Jefferson Davis in a game of chess. Davis had just fled Richmond, Virginia after the Confederate surrender by Robert E. Lee.
He received his M.D. degree from the University of Virginia in 1877 and also received an M.D. from the University of the City of New York in 1877.
