Leo and Diane Dillon are a prolific American husband and wife team of
illustrators. Among their many awards are two back to back Caldecott Medals
for the children's books Why Mosquitoes Buzz In People's Ears and Ashanti To
Zulu: African Traditions.
Leo was raised in Brooklyn, and Diane in the Los Angeles area. They met at
the Parsons School of Design in New York City in 1953, some time after Diane
moved from California to New York. They graduated from Parsons in 1956, and
eventually married in March 1957. They describe their work as incorporating
motifs derived from their respective heritages. They have worked on both on
children's literature and adult paperbacks. An association with writer Harlan
Ellison led to jobs doing book covers for his short story collections and
both cover and interior woodcut illustration for his anthology Dangerous
Visions. Other jobs in the science fiction field include every one of their
covers for the original Ace Science Fiction Specials.
A detailed biography and introduction to their work and styles was written by
Byron Preiss in a book he edited in 1981, The Art of Leo & Diane Dillon.
