Did you know the idea of Father's Day was conceived slightly more than a century ago by Sonora Dodd of Spokane, Wash., while she listened to a Mother's Day sermon in 1909. Dodd wanted a special day to honor her father, William Smart, a widowed Civil War veteran who was left to raise his six children on a farm. A day in June was chosen for the first Father's Day celebration, June 17, 1910, proclaimed by Spokane's mayor because it was the month of Smart's birth. The first presidential proclamation honoring fathers was issued in 1966 when President Lyndon Johnson designated the third Sunday in June as Father's Day. Father's Day has been celebrated annually since 1972 when President Richard Nixon signed the public law that made it permanent.
