The Robinson family is a fictional family in the children's television series Sesame Street. The family consists of high school science teacher Gordon and his wife, Susan, a nurse. Later, the family expands to include their adopted son, Miles, as well as Gordon's sister, Olivia, his father, Mr. Robinson, and a brother. As African Americans, the family was created as leads for the show, originally targeted to underprivileged inner city children. Even as human roles were slowly reduced over the years, their characters maintained a constant presence.
