In 1953, Rogers returned to Pittsburgh to work as a program developer at public television station WQED. Josie Carey worked with Rogers to develop the children's show The Children's Corner, which Carey hosted. He worked off-camera with Carey to develop the puppets, characters, and music for show. Rogers used many of the puppet characters developed during this time, such as Daniel the Striped Tiger (named for WQED's station manager, Dorothy Daniel, who gave Rogers a tiger puppet before the show's premiere), King Friday XIII, Queen Sara Saturday (named for Rogers' wife), X the Owl, Henrietta, and Lady Elaine, in his later work. Children's television entertainer Ernie Coombs was an assistant puppeteer. The Children's Hour won a Sylvania Award for best locally produced children's show in 1955 and was broadcast nationally on NBC. While working on The Children's Hour, Rogers attended Pittsburgh Theological Seminary, and was ordained as a Presbyterian minister in 1963. He also attended the University of Pittsburgh's Graduate School of Child Development, when he began working with child psychologist Margaret McFarland, who according to Rogers biographer Maxwell King, became his "key advisor and collaborator" and his "child-education guru". Much of Rogers' "thinking about and appreciation for children was shaped and informed" by McFarland. She was his consultant for most of Mister Rogers' Neighborhood's scripts and songs for 30 years.
