Father's Day
Father's Day was not celebrated in the US, outside Catholic traditions, until the 20th century. As a civic celebration in the US, it was inaugurated in the early 20th century to complement Mother's Day by celebrating fathers and male parenting.
After Anna Jarvis' successful promotion of Mother's Day in Grafton, West Virginia, the first observance of a "Father's Day" was held on July 5, 1908, in Fairmont, West Virginia, in the Williams Memorial Methodist Episcopal Church South, now known as Central United Methodist Church. Grace Golden Clayton was mourning the loss of her father, when in December 1907, the Monongah Mining Disaster in nearby Monongah killed 361 men, 250 of them fathers, leaving around a thousand fatherless children. Clayton suggested that her pastor Robert Thomas Webb honor all those fathers.
Spokane, Washington
Spokane is known as the birthplace of the national movement started by Sonora Smart Dodd that led to the proposal and eventual establishment of Father's Day as a national holiday in the U.S. The first observation of Father's Day in Spokane was on June 19, 1910. Sonora conceived the idea in Spokane's Central Methodist Episcopal Church, while listening to a Mother's Day sermon.
