Charles Harris Kuhn (March 20, 1892 – 1989), nicknamed Doc Kuhn, was a cartoonist best known as the creator of the comic strip Grandma. He usually signed his drawings and comic strips Chas. Kuhn. Born in Prairie City, Illinois, he was the son of James B. and Minnie Harris Kuhn. His father ran a restaurant and proudly displayed his son's drawings in the eatery's window. At age 12, he decided to become a cartoonist when the sale of his first cartoon brought him 50 cents. Kuhn grew up in Bushnell, Illinois, and later remarked, "I hope some of the oldtimers remember me as a regular fellow."
