While attending a Bronx, New York, grade school, Prelutsky took piano and voice lessons and was a regular in school shows. Surprisingly, Prelutsky developed a healthy dislike for poetry due to a teacher who "left me with the impression that poetry was the literary equivalent of liver. I was told it was good for me, but I wasn't convinced."
In his early twenties, Prelutsky spent six months drawing imaginary animals in ink and watercolor. One evening, he wrote two dozen short poetry verses to accompany each drawing. A friend encouraged him to show them to an editor, who loved his poems (although not his artwork!) and urged him to keep writing. Prelutsky listened and he is still busy writing.
Jack Prelutsky lives on Mercer Island in Washington with his wife, Carolynn.
