David Abraham Adler (born April 10, 1947) is the author of nearly 200 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 City, 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 published that year.
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.
Adler has three children and one grandson. He lives in Woodmere, New York.
Robert Casilla was born in Jersey City, New Jersey to parents from Puerto Rico. Like many children, Robert always loved to draw. As the new kid in his second grade class, he recalls doing a drawing of two birds with colored chalk on construction paper. His teacher noticed the drawing and then told the class, "We have an artist in the class!" Robert is thankful to her and all the teachers that motivated and helped him realize he had talent as an artist. Although he grew up in New Jersey, he did get to attend school in Puerto Rico as a fourth grader.
His formal training in art took place at the School of Visual Arts in New York City where he earned a BFA degree.
Since 1984, Robert has worked as a freelance illustrator for magazines, book publishers, postage stamps, educational publishers and others.
He has illustrated over 25 children's books, many of which are picture book biographies of people such as Martin Luther King, Jr., Jackie Robinson, Rosa Parks and John F. Kennedy. He has also illustrated many multicultural children's books such as Jalapeno Bagels, The Little Painter of Sabana Grande, The Legend of Mexicatl and First Day in Grapes which won the Pura Belpré Honor Award.
Robert visits many schools to talk about the visual journey a story takes him through to come up with the illustrations for his books. He also teaches art to young gifted artist one day a week.
Robert lives and works from his home in New Fairfield, Connecticut with his wife and two children, 3 cats and his feisty shih tzu dog.
