* The earliest roots of Looney Tunes can be traced back to Bob Clampett, who worked on the earliest Warner Bros. cartoons featuring Bugs Bunny and Daffy Duck. He helped solidify their personalities and introduced many of their signature gags.
* The official launch of Looney Tunes as a series is credited to Leon Schlesinger, the head of Warner Bros. Cartoons. He gave the green light to a series of animated shorts featuring various characters.
* Many other animators, writers, and directors contributed to the development of Looney Tunes, including Robert McKimson, Chuck Jones, Friz Freleng, and Tex Avery. Each brought their own unique style and vision to the characters and stories, contributing to the diverse and iconic nature of Looney Tunes.
So, while no single individual can be credited with "inventing" Looney Tunes, it was the collective work of talented individuals that brought these beloved characters to life.
