Olivia Robinson is a resident of Sesame Street who made her profession as a photographer. She first appeared in Episode 0950 where she's reunited with her older brother Gordon after having worked in Detroit for a newspaper. She was "welcomed" to Sesame Street by Oscar the Grouch a week later when she started looking for a job. It's established in the song "Little Sister is a Big Girl Now" that she is three years younger than Gordon.
Olivia appeared on Sesame Street from 1976 (Season 8) to 1988 (Season 19), though she was occasionally shown in repeated material for a few years after (and as a child in flashbacks in Episode 2621 and 2965). During her time on the show, she resided in Gordon and Susan's apartment. In the 1985 film Follow That Bird, she searches for Big Bird with Gordon, Linda, Cookie Monster, and Grover in a yellow Volkswagen bug.
As a photographer, she used the basement of 123 Sesame Street as her darkroom (as early as Episode 1359). Later in Episode 1749, she commandeered part of the Carriage house to use as her personal photo studio.
Some of her notable appearances on the show include comparing photography with Oscar in Episode 1217, taking Herry Monster to (and inspiring him to become) an eye doctor in Episode 1261, dating a piano tuner named Bernie in Episode 1859, teaching Big Bird how to vote in Episode 1957, performing at Birdland in Episode 2304 and Episode 2447, and singing opera with Placido Flamingo in Episode 2317.
She was also present for several milestones on Sesame Street, including Miles' adoption, the Trip to Hawaii and Trip to Puerto Rico, helping to explain Mr. Hooper's death to Big Bird in Episode 1839, and searching for Big Bird in the Metropolitan Museum of Art in Don't Eat the Pictures with some kids.
In the tradition of Sesame Street characters reading a story acted out by Muppets, Olivia has read "The Two-Headed Monster" (in which the Two-Headed Monster is named Horn and Hardart), "Katie and the King", and "How the King Got His Kazoo."
