Rev. Foy has put to together a extremely overdue and enlightening book, that in the publishers humble opinion, should be in every home, library, and school in this country! The material in this book is simply astounding and many of these discoveries have not been attributable to Blacks. In fact, during these times, Blacks could not have their names listed on the patents for their own inventions. But other records were kept nevertheless. Now, Mr. Foy has extensively documented historical findings factually showing patented inventions created by people of African heritage that today, we take as modern conveniences.
