After serving as a flight surgeon in the U.S. Air Force in the 1960s, Dr. Paul moved to Texas to begin a civilian medical practice, delivering over four thousand babies in his career as an obstetrician. He served in Congress from 1976 to 1984, and again from 1996 to 2012. He and Carol Paul, his wife of fifty-one years, have five children, eighteen grandchildren, and one great-grandchild.

Ron Paul, the New York Post once wrote, is a politician who "cannot be bought by special interests."
