It is thought that Father's Day began in the year of 1909 when Sonora Louise Smart Dodd, after hearing mass on Mother's Day, realized that fathers like her dad, William Jackson Smart, should also be honored and given a special day. Her Father was unique. He raised six kids all by himself after her Mother had passed on. And so on June 19, 1910 – the day of Daddy Smart's birthday – the first celebration of Father's Day occurred.
