Beverly Cleary was inadvertently doing market research for her books before she wrote them, as a young children¿s librarian in Yakima, Washington. Cleary heard a lot about what kids were and weren¿t responding to in literature, and she thought of her library patrons when she later sat down to write her first book.

Henry Huggins, published in 1950, was an effort to represent kids like the ones in Yakima and like the ones in her childhood neighborhood in Oregon. The bunch from Klickitat Street live in modest houses in a quiet neighborhood, but they¿re busy: busy with rambunctious dogs (one Ribsy, to be precise), paper routes, robot building, school, bicycle acquisitions, and other projects. Cleary was particularly sensitive to the boys from her library days who complained that they could find nothing of interest to read ¿ and Ralph and the Motorcycle was inspired by her son, who in fourth grade said he wanted to read about motorcycles. Fifteen years after her Henry books, Cleary would concoct the delightful story of a boy who teaches Ralph to ride his red toy motorcycle.

Cleary¿s best known character, however, is a girl: Ramona Quimby, the sometimes difficult but always entertaining little sister whom Cleary follows from kindergarten to fourth grade in a series of books. Ramona is a Henry Huggins neighbor who, with her sister, got her first proper introduction in Beezus and Ramona, adding a dimension of sibling dynamics to the adventures on Klickitat Street. Cleary¿s stories, so simple and so true, deftly portrayed the exasperation and exuberance of being a kid. Finally, an author seemed to understand perfectly about bossy/pesty siblings, unfair teachers, playmate politics, the joys of clubhouses and the perils of sub-mattress monsters.

Cleary is one of the rare children¿s authors who has been able to engage both boys and girls on their own terms, mostly through either Henry Huggins or Ramona and Beezus. She has not limited herself to those characters, though. In 1983, she won the Newbery Medal with Dear Mr. Henshaw, the story of a boy coping with his parents¿ divorce, as told through his journal entries and correspondence with his favorite author. She has also written a few books for older girls (Fifteen, The Luckiest Girl, Sister of the Bride, and Jean and Johnny) mostly focusing on first love and family relationships. A set of books for beginning readers stars four-year-old twins Jimmy and Janet.

Some of Cleary¿s books ¿ particularly her titles for young adults ¿ may seem somewhat alien to kids whose daily lives don¿t feature soda fountains, bottles of ink, or even learning cursive. Still, the author¿s stories and characters stand the test of time; and she nails the basic concerns of childhood and adolescence. Her books (particularly the more modern Ramona series, which touches on the repercussions of a father¿s job loss and a mother¿s return to work) remain relevant classics.

Cleary has said in an essay that she wrote her two autobiographical books, A Girl from Yamhill and My Own Two Feet, "because I wanted to tell young readers what life was like in safer, simpler, less-prosperous times, so different from today." She has conveyed that safer, simpler era -- still fraught with its own timeless concerns -- to children in her fiction as well, more than half a century after her first books were released.
