* The animated Pink Panther: The character of the Pink Panther was created by David DePatie and Friz Freleng, who were the founders of DePatie-Freleng Enterprises. They created the character for the opening credits of the 1963 film "The Pink Panther" starring Peter Sellers.
* The Pink Panther film series: The first Pink Panther film, as mentioned above, was "The Pink Panther" (1963) directed by Blake Edwards.
* The Pink Panther books: There is no single author for all the Pink Panther books. There have been many books written about the Pink Panther, featuring stories, adaptations of the films, and even a graphic novel series. You'd need to specify which book you're interested in to determine its author.
I hope this clears up the confusion!
