David Abraham Adler (born April 10, 1947) is an American writer of 265 books for children and young adults, most notably the Cam Jansen mystery series, the "Picture Book of..." series, and several acclaimed works about the Holocaust for young readers.

In that same year, a question from his then-three-year-old nephew inspired Adler to write his first story, A Little at a Time, subsequently published by Random House in 1976.

Adler married psychologist Renee Hamada in 1973, and their first child, Michael, was born in 1977.

By that time Adler had taken a break from teaching and, while his wife continued her work, he stayed home, took care of Michael, and began a full-time writing career.

In January 2016, Adler (together with illustrator Sam Ricks) won the prestigious Theodor Seuss Geisel award for the 2015 book Don't Throw It To Mo!

For thirty years my parents kept in an otherwise unused room unwanted wedding gifts belonging to a relative who had moved overseas -- an electric fan, dishes with a strange bird pattern, luggage, pots, and lots of cups and glasses.

When he left, I had all those questions swirling in my head and that led to my very first published story, A Little At A Time.

I was granted a child-care leave from teaching and while I was caring for my infant son, I created Cam Jansen.

A series of books following the exploits of a fifth-grade female detective named Jennifer "Cam" Jansen and her best friend Eric.

Nicknamed Cam for her photographic memory, the protagonist closes her eyes and says "click" at various points in a story, mimicking the noise of a camera while memorizing a scene in front of her.

The Cam Jansen character was based on an elementary school classmate of Adler's who was believed to have a photographic memory.

A stage musical based on the character Cam Jansen and novels was produced by Theatreworks USA Off-Broadway in 2004.
