This book documents a number of inventions, patents and labor saving devices conceived by Black inventors from over 70 countries. 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 Although historical documents emphasize that millions of Black people arrived in Canada, the Caribbean, Central and South America and the United States under slavery's yoke, it is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.
