In 1909, Mrs. John B. Dodd, of Spokane Washington, first proposed the idea of a "Father's Day". Mrs. Dodd wanted a special day to honor her father, William Smart. William Smart, a Civil War veteran, was widowed when his wife died in childbirth with their sixth child. Mr. Smart was left to raise all his children alone on a rural farm in eastern Washington state.

The first Father's Day was observed on June 19, 1910 in Spokane Washington. Mrs. Dodd wanted Father's Day to be celebrated on the first Sunday in June, her father's birthday. However, the Spokane council couldn't get the resolution through the first reading until the third Sunday in June. At about the same time in various towns and cities across American other people were beginning to celebrate a "father's day." In 1924 President Calvin Coolidge supported the idea of a national Father's Day. Finally in 1966 President Lyndon Johnson signed a presidential proclamation declaring the 3rd Sunday of June as Father's Day.
