Mike Twohy has been drawing cartoons as far back as he can remember. The author and illustrator of Poindexter Makes a Friend, Outfoxed, and Wake Up, Rupert!, he received his MFA in painting in 1973 from the University of California, Berkeley. In 1980 his first drawing was published in The New Yorker, which has published his cartoons regularly ever since. In a starred review, School Library Journal praised his first book, Pointdexter Makes a Friend, as a "reassuring story [that] will envelop youngers like a warm, cozy blanket." He lives with his wife, cat, and Newfoundland in Berkeley, California.
