Fred McFeely Rogers (1928-2003) was a passionate advocate for children who taught that everyone is unique and deserving of love and respect "just the way you are". For more than 30 years he used his public television program Mister Rogers' Neighborhood as a vehicle of service to the youngest members of the human family.
