Black Inventors, Crafting Over 200 Years of Success, highlights the work of Black inventors from over seventy countries. The author, Keith C. Holmes, has spent more than twenty years researching Black inventors from countries that include Australia, Bahamas, Barbados, Canada, Cuba, Ethiopia, France, Germany, Ghana, Dominican Republic, Guadeloupe, Guyana, Haiti, Italy, Jamaica, Japan, Kenya, Mozambique, Nigeria, St. Vincent, South Africa, Tanzania, Trinidad and Tobago, the United Kingdom and the United States. Without inventions, innovations, financial resources, materials, muscle and labor saving devices, civilizations cannot exist and flourish. This book documents a number of inventions, patents and labor saving devices conceived by Black inventors. Among many other inventions, pre-enslaved Africans, developed agricultural tools, building materials, medicinal herbs, cloth and weapons. Although historical documents emphasize that millions of Black people arrived in Canada, the Caribbean, Central and South America and the United States under slavery's yoke, it is relatively unknown that thousands of Africans and their descendants developed numerous labor-saving devices and inventions that spawned companies which generated money and jobs, worldwide. While most authors focus primarily on American and European inventors, Keith Holmes introduces inventions, both past and present, that Black people, developed and patented globally and multiculturally.Black Inventors, Crafting Over 200 Years of Success, also features early Black inventors from virtually every state in the US. It includes details about the first Black inventor who obtained a patent in both the Caribbean and the United States. To date, seventeen African American men have been inducted into the National Inventors Hall of Fame. Two inventors, Jan E, Matzeliger, (Suriname) and Elijah McCoy, (Colchester, Canada) were not born in this countryThe material available in this book, one of the first to address the diversity of black inventors and their inventions from a global perspective, effectively gives the reader, researcher, librarian, student, and teacher the materials they need to understand that the Black inventor is not only a national phenomenon, but also a global giant.

"From this lively and personal account, we learn that we can all practice inventorship to great advantage-measured either in gold or pleasure, or perhaps both!"-From the Foreword by Walter Cronkite "Inventorship is truly the stuff from which the future will be molded. Giving us an insight into the everyday thought processes of great inventive minds, Greene's wonderful collection of stories and ideas is a model for each of us in the art of inventiveness."-Pat Hallberg, Executive Director, National Inventors Hall of Fame "This entertaining and well-written work educates without pain and motivates the reader to learn more. It should be widely read not only by business people and entrepreneurs, but by young people, their parents, and their teachers. The lesson: Inventorship is for everyone and can change lives for the better."-Joseph N. Hankin, President, Westchester Community College "After all the scholarly books and articles about innovation and the entrepreneurial process by theorists, how refreshing it is to hear from a real live inventor holding hundreds of patents in fields as diverse as aeronautics, sailing, chess, and skiing! He has even invented a word, 'inventorship', to describe the process and guide us through dozens of examples. A very useful book."-John Diebold, Chairman, The JD Consulting Group, Inc.
