A few years after his birth, which was, incidentally, May 12, 1971, in the tumbleweed town of Abilene, Texas, CS Jennings discovered the pencil and crayon. Thus began his artistic career. Early subjects included clowns, after that, pirates. In elementary school he honed his skills on the drawing of horses (though it is widely rumored he drew them only because of their popularity with the elementary school dames). He drew knights. He drew cats. Then cats in rock bands. Then cats with mad karate skills. Shark comics. Suicide mouse comics. Indeed, he was prolific in his early work.

He obtained his degree in Design Communication with a private study in Illustration from the University of Central Oklahoma. While at the university he drew a cartoon strip and editorial cartoons for the school's newspaper. (His series on political correctness was utilized by the university's debate team, though to what effect, he never knew.) He was Awarded Outstanding Art Student of the Year in 1994. That same year he won an Addy Award for illustration work in the school's promotional piece.

For four years he was the Fort Worth Star Telegram's sports editorial cartoonist and continues to contribute to the paper. He has provided illustrations for several magazines and children's publications. Most recently, he was an animation lead for Richard Linklater's animated film, A Scanner Darkly (to be released in March, 2006). As an experienced freelance illustrator working in the publishing industry, operating within deadline specs and quick turnarounds are his specialty.

CS Jennings currently resides in Austin, Texas.
