However, a book entitled "When Harlem was Jewish:1870-1930" by Jeffrey S. Gurock, a professor at Yeshiva University, may contain information about the Harlem Preparatory School and/or the Harlem Evening High School for Men.
I have the book and neither name (Harlem Preparatory School or Harlem Evening High) appears in the index.
