Stephen Marchesi is an artist who lives in New York. He has created illustrations for textbooks, magazines, and children's books.

As a child, Marchesi drew his own comics. While a student at High School of Art and Design, he worked for Warren Publications. In 1973 he graduated from Pratt Institute. Afterward he spent half a year working as an assistant art director for an ad agency, and then began his career as a freelance illustrator. Marchesi cited his primary influences as being the cover illustrations and interior artwork created by Newell Convers Wyeth for novels published by Charles Scribner's Sons, and movie posters of the 1950s and 1960s.

In 1978 Marchesi was hired by Random House to create new cover art for 12 of the paperback editions of its Three Investigators series. Of the nearly 500 book covers that Marchesi has illustrated, he said that he had more freedom while doing these 12 than for any others that he has ever done. These covers were also the last time that he used watercolor - he later switched to acrylic and oil.

Everyone loves Harry Potter. Now kids can learn about Harry's creator!

In 1995, on a four-hour-delayed train from Manchester to London, J. K. Rowling conceived of the idea of a boy wizard named Harry Potter. Upon arriving in London, she began immediately writing the first book in the saga. Rowling's true-life, rags-to-riches story is as compelling as the world of Hogwarts that she created. This biography details not only Rowling's life and her love of literature but the story behind the creation of a modern classic.
