(Excerpt: "Leo and Diane Dillon have been producing stunning
illustrations for books, album covers, posters, advertisements and
other media since 1957. Today they are prolific as ever. This husband
and wife collaborative team are the only artists to win the
prestigious Caldecott medal for childrens book illustrations two years
in a row, in 1976 for Why Mosquitos Buzz in People's Ears and in 1977
for Ashanti to Zulu; Leo Dillon was the first African-American artist
to win that award (1976). They have also won the Hamilton King award,
the Gold Medal for Childrens Book Illustration from the Society of
Illustrators, and the Hugo in 1971 award for science fiction book
illustration.")
