Jon McClenahan is an American animator, hailing from Chicago, Illinois.
Jon's career in animation began in 1980, This was when he was told of a job opening at Hanna-Barbera's Australian offices after 4 years of working as a truck driver. He and his family left for Sydney promptly to work at the studio. He started as an inbetweener, eventually climbing the ladder to direct the animation for animated adaptations for The Berenstain Bears and Teen Wolf.
His employment at HB Southern Star Studios (as it was called) ended in August 1987, when the studio was consolidated and sold off. After some time at Cioni Artworks, Jon started StarToons, his studio, located in Chicago. During this time, he did some of his best known works, including Tiny Toon Adventures (some Kennedy Cartoons animated episodes, and some of his own), Taz-Mania, and, ultimately, Animaniacs, for which he did most of the Slappy Squirrel shorts.
However, after completing work on the first season of Animaniacs, StarToons began sliding into a downwards spiral. Jon planned with one of his former background painters, an Indian named Uttam Kumar, to start an Indian animation house for StarToons (which was to be the first of its kind) only for Kumar to be found out as having undergone a Face Heel Turn during that time. Later, after a management change at Warner Bros. Animation (his client for nearly all of StarToons' work), Jon tried to get on good terms with new president Sander Schwartz, only to be accused of shipping the work to an overseas studio just because it was so different from what StarToons usually did. This was the death knell to StarToons, and Jon McClenahan was on his own again.
After a brief stint at Germany's Munich Animation, he became a director at Midway Games until 2006. After that, he had a two-year stint at Star Farm Productions.
Now, since 2008, Jon McClenahan once again has his own company, named Mack Hammer Productions, which mainly does storbboards and character designs for miscellaneous shows. However, he keeps a low profile, and he posts on the Toon Zone forums as Jonny Mack.
