Georgetown University law professor Randy Barnett has played an integral role in the rise of originalism—the movement to identify, restore, and defend the original meaning of the Constitution. But Barnett’s path to becoming an influential professor of constitutional law was not an easy one. Starting from a working-class childhood in Calumet City, Illinois, Barnett’s unusual resume has included stints as an ice cream truck driver, newspaper ad salesman, prosecutor, libertarian theorist, contract law professor, and Supreme Court advocate. In his new autobiography, A Life for Liberty, Barnett tells the complete story of his personal and professional journey.
