Historians are just beginning to uncover some of the ways in which African Americans have contributed to the development of American technology. Seventeenth-century African-American inventors left no written records of their own. But many of them were skilled in crafts and created new devices and techniques in the course of their work. Africans brought a store of technological knowledge with them to the Americas. In the West elements of African technology merged with European and Native American technology to create new American traditions in technology. This is particularly evident in the areas of boat building, rice culture, pharmacology, and musical instrument making.
More is known about black inventors in the eighteenth and nineteenth centuries, particularly those who enjoyed some celebrity in their time, such as Norbert Rillieux, a Louisianan who invented the multiple-effect vacuum evaporation system for producing sugar from sugar cane. The Rillieux method revolutionized the sugar industry and came to be the accepted method of sugarcane juice evaporation. Though blacks contributed to the technological development that resulted, there was little public recognition of their achievements.
In the North many African-American men turned to the maritime trades for employment, and from these ranks came several outstanding inventors such as James Forten, the wealthy Philadelphia black abolitionist whose fortune was built upon his invention around the turn of the nineteenth century of a sail-handling device, and Lewis Temple, who introduced the toggle harpoon to commercial whaling in Massachusetts in the 1840s.
Craftsmen who invented new devices discovered innovative techniques that improved the quality of their products or reduced the cost of producing them often went into business for themselves instead of hiring themselves
out for wages. But these craftsmen-inventors still faced the problems of patenting the invention or protecting it somehow from competitors, financing its production, and marketing it.
The enactment of the U.S. Patent Act in 1790 provided for some documentation of black inventors and their inventions, but this documentation is incomplete. Because the race of the inventor was not generally recorded by the U.S. Patent Office, it is not known for certain how many blacks received patents. Thomas L. Jennings, a New York abolitionist, is the earliest African-American patent holder to have been identified so far. He received a patent for a dry-cleaning process on March 3, 1821. Further research may uncover earlier black patent holders. Slaves were legally prohibited from receiving patents for their inventions, and there are few surviving accounts in which slave inventors are fully identified. …
An invention introduces us to a new thing. A Discovery finds something which is already there, but we have not known about it.
I adore great scientists like Newtons, Edison, Chandra Shekhar, JC Bose, CV Raman, Eintstein, Archmedis, Pascal, Bernouli, Arya Bhatta, Curie, B Gates, Thomson.
Invention of the semiconductor transistor by Bardeen, Brattain and William Schockley has lead to the most sophisticated computers, laptops, cell phones, calculators etc. Every electronic device makes use of their invention.
To be an inventor one needs to be creative, objective, have analytical capacity, mathematically good, ability to correct own faults and to work alone. Often inventors take the challenge in front of them to find solutions.
Inventors dedicated their lives to their field and to the good of mankind. Many of them sacrificed their personal life and made our life on Earth today comfortable.
I wish to be an Inventor of a great concept/gadget that changes the world.
Thanks for listening to me attentively.
