Shalleck to work for
CBS in the 1950s, eventually becoming an associate producer on the children's television series
Winky Dink and You. In the early sixties he moved to Montreal where he produced "Like Young", at CFCF-TV, a highly successful teen music/dance show starring Jim McKenna that was eventually picked up and syndicated by Dick Clark Productions. Following his years at CBS, and CFCF-TV Shalleck was a producer at The Network for Continuing Medical Education and then formed his own production company (AJ Shalleck Productions) and produced a number of low-budget children's animated films and television episodes. In 1977, he approached
Margret Rey about producing a television series based on Curious George, which led to the 1980 television show. Shalleck and Rey wrote more than 100 short episodes for the series. In addition, they collaborated on a number of children's books and
audiobooks. (Some of these books list Rey as the author and Shalleck as the editor, while others reverse the credits.) In his retirement, Shalleck lived in Florida and created the company "Reading By GRAMPS" and visited local elementary schools, bookstores, and other events to read books to children and promote literacy. However, he also experienced financial problems and was forced to supplement his income with part-time jobs, including working as a bookseller at a local
Borders Books. ==Personal life==
