History in Brief

Big Brothers Big Sisters of America’s roots date to 1904, when Ernest Coulter, a New York City court clerk, established Big Brothers to match caring adults with young people who were getting into trouble. At the same time, members of Ladies of Charity were befriending girls who had come through the New York Children’s Court. That group would later become Catholic Big Sisters, and subsequently, Big Sisters International. These groups worked independently until 1977, when Big Brothers Association and Big Sisters International joined forces and became Big Brothers Big Sisters of America. Big Brothers Big Sisters International was founded in 1998, and now serves children in 12 countries.
