Sandra Boynton, 59, is a creative whirlwind known for her songs, her whimsical greeting cards (like “Hippo Birdie Two Ewes”), and her funny board books. Check out Pajama Time!, Moo, Baa, La La La! and Blue Hat, Green Hat. (Get ready to say, “oops” to a shoe on a head!) Boynton and her husband, fellow Yale alum James McEwan, a former Olympic slalom canoe racer, are the parents of four. Here the author/illustrator and her mother appear together in 2005 during her “Dog Train” book and CD release party in New York City.
