William Clement Frawley (February 26, 1887 – March 3, 1966) was an American stage entertainer, screen and television actor. Although Frawley acted in over 100 films, he is best known for playing landlord Fred Mertz in the situation comedy I Love Lucy, and "Bub" in the TV series My Three Sons. William was born to Michael A. Frawley and Mary E. Brady in Burlington, Iowa. As a young boy, Bill (as he was commonly called) attended Roman Catholic school and sang with the St. Paul's Church choir. As he got older, he loved playing bit roles in local theater productions, as well as performing in amateur shows. However, his mother, a religious woman, discouraged the idea. William did two years of office work at Union Pacific Railroad in Omaha, Nebraska. He later relocated to Chicago and found a job as a court reporter. Soon thereafter, against his mother's wishes, Frawley obtained a singing part in the musical comedy The Flirting Princess. To appease his mother, Bill relocated to St. Louis, Missouri, to work for another railroad company. Unhappy with his railroad job, Frawley longed to be an actor.
