Barron that spark came from a mimeograph machine in the basement of his Brooklyn, NY, bookstore in the late 1930s. People from the community asked Mr.

Barron for books to help their children study for the New York State Regents exams. After realizing there wasn't anything available, Mr. Barron created his own study guides.
