Thanks For A Nice Fathers Day - Here Is Its History

From Wikipedia

Sonora Louise Smart was born in Jenny Lind, Sebastian County, Arkansas to farmer William Jackson Smart (1842-1919) and his wife Ellen Victoria Cheek Smart (1851-1898). William Smart was a sergeant in the Union's First Arkansas Light Artillery during the Civil War. When Sonora was seven years old, the Smart family moved from Marion, Arkansas to a farm between Creston, Washington and Wilbur, Washington [near Spokane] in 1889.
When Sonora was 16, her mother died in childbirth with her sixth child. Sonora was the only daughter and shared with her father William in the raising of her younger brothers, including her new infant brother Marshall. Sonora Smart married John Bruce Dodd (1870-1945), one of the original founders of Ball & Dodd Funeral Home, and had a son, Jack Dodd, born in 1909.

Father's Day

Smart held her father in great esteem. While hearing a church sermon about the newly recognized Mother's Day at Central Methodist Episcopal Church,^[3] Sonora felt strongly that fatherhood needed recognition as well. She approached the Spokane Ministerial Alliance and suggested her own father's birthday, of June 5, as the day of honor for fathers. The Alliance chose the third Sunday in June instead.
The first Father's Day was celebrated June 19, 1910 in Spokane, Washington.
