Jane Yolen started writing poems before she got to school. She wrote the class musical in first grade — both words and music. It was about a bunch of vegetables who got together in a salad. Jane played the chief carrot! While she was in junior high, Jane wrote an entire essay in rhyme about manufacturing in New York State. In high school, she won a Scholastic poetry contest. In college, she wrote newspaper articles and songs.
As with all great discoveries, Mark Teague's eureka moment materialized from something seemingly unrelated, when a move from San Diego to New York City planted the seed for his first picture book, The Trouble with the Johnsons. His debut earned him a feature in Publishers Weekly as one of eleven prominent new authors of 1989 and secured his place among beloved children's authors.
