'Chicka Chicka Boom Boom' illustrator Lois Ehlert dies at 86

MILWAUKEE (AP) - Lois Ehlert, whose cut-and-paste shapes and vibrant hues in books including 'œChicka Chicka Boom Boom'ť put her among the most popular illustrators of books for preschoolers of the late 20th century, has died. She was 86.

Publisher Simon & Schuster said that Ehlert died of natural causes on Tuesday in Milwaukee.

In 1989's 'œChicka Chicka Boom Boom,'ť Ehlert created the hyper-simple brown-and-green coconut tree and the multicolored capital letters who try to gather at the top of it, threatening to bring it tumbling to the ground as the text repeats, 'œChicka chicka boom boom! Will there be enough room?'ť

The book sold more than 12 million copies, according to Simon & Schuster.

She worked primarily by cutting out shapes and pasting them into collages, much like the preschoolers who were her primary audience.

In 1990, she was given a Caldecott Honor as the author and illustrator of 'œColor Zoo,'ť which uses basic triangles, rectangles, squares and circles to create images of animals in oversaturated oranges, purples and greens. Its only words are the names of the shapes and creatures themselves.

Ehlert was born in Beaver Dam, Wisconsin and graduated from Milwaukee's Layton School of Art. She worked in graphic design before she began illustrating children's books in her 50s, starting with 1987's 'œGrowing Vegetable Soup.'ť

Her other books include 1988's 'œPlanting a Rainbow,'ť 1989's 'œEating the Alphabet'ť and 2001's 'œWaiting for Wings.'ť
