Father's Day was first celebrated in 1910 in Spokane Washington. After hearing a a sermon about Mother's Day, a young woman named Sonora Smart Dodd went to her pastor and told him that fathers should also have a holiday to honor them.
Her father, a Civil War here, was a single parent who raised six children after his wife died in childbirth. It was his selfless and constant attention to his children that inspired Dodd to campaign for Father's Day.
It took decades for the holiday to receive the recognition that she had hoped for. In 1966 Lyndon B. Johnson finally proclaimed the 3rd Sunday in June as Father's Day, and in 1976 it was made a national holiday, signed into law by Richard Nixon. Wikipedia
Bill Cosby, a man who has long entertained us with his perspective on fathers, said:
"If the new American father feels bewildered and even defeated, let him take comfort from the fact that whatever he does in any fathering situation has a fifty percent chance of being right."
Fatherhood is a challenging endeavor, and the on-the-job training is arduous. It often isn't until we're adults that we really see the heroes fathers have been in our lives.
