Stanley Berenstain and Janice Grant met in 1941, on their first day of drawing class at the Philadelphia Museum School of Industrial Art, where they formed an immediate bond. After being separated during World War II, during which Stan worked for the Army as a medical illustrator and Janice worked as a riveter, they were reunited and married in 1946. While initially working as art teachers, the Berenstains pursued a joint career in cartooning and gradually found success working together on illustrations, humorous sketches and cover art for publications including The Saturday Review of Literature, Collier’s, McCall’s, Good Housekeeping, and The Saturday Evening Post. In 1951, they published Berenstains’ Baby Book, a humorous how-to aimed at adults and based on their experiences raising their infant son Leo in downtown Philadelphia. Nearly two dozen other books followed; described by Stan as “cartoon essays,” the titles included Marital Blitz, How To Teach Your Children About Sex Without Making A Complete Fool of Yourself and Have A Baby, My Wife Just Had A Cigar!
