People like David A. Adler

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.

Adler was born in New York. He graduated from Queens College in 1968 with a bachelor's degree in economics and education. For the next nine years, he worked as a mathematics teacher for the New York City Board of Education, while taking classes towards a master's degree in marketing, a degree he was awarded by New York University in 1971. 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's next project, a series of math books, drew on his experience as a math teacher. In 1977, he created his most famous character, Cam Jansen, originally featured in Cam Jansen and the Mystery of the Stolen Diamonds, which was first published in 1980 and is still in print along with more than 50 other Cam Jansen Mysteries. Worldwide, more than 30,000,000 Cams have been printed and sold.
