4.Touch-Tone Phone

Shirley Ann Jackson made several telecommunications breakthroughs while employed with Bell Laboratories. Her scientific discoveries led to the touch-tone phone, caller I.D. and call waiting. Jackson was also the first black woman to graduate with a Ph.D. from M.I.T.

3-D Effect

5.Computer graphics designer Marc Hannah co-founded Silicon Graphics, Inc. His computer programs were instrumental in the creation of special effects for films like “Jurassic Park,” “Aladdin,” “Beauty and the Beast” and more.

6.The Blood Bank

African American physician Charles Drew developed a way to process and preserve blood plasma, which lasts much longer than actual blood.

Numero sold his movie sound equipment business to RCA and formed a new company in partnership with Jones, the U.S. Thermo Control Company (later the Thermo King Corporation ) which became a $3 million business by 1949.

9.Lawn Mower

If you have a manual push mower today, it likely uses design elements from 19th Century black American inventor John Albert Burr’s patented rotary blade lawn mower.On May 9, 1899, John Albert Burr patented an improved rotary blade lawn mower. Burr designed a lawn mower with traction wheels and a rotary blade that was designed to not easily get plugged up from lawn clippings.

Imhotep, an egyptian physician was revered in ancient Egypt.His medical challenges necessitated the invention of the stethoscope. As a god of medicine, Imhotep was beloved as a mediator of everyday problems who could “provide remedies for all diseases,” and “give sons to the childless.” Members of the cult of Imhotep in the Twenty-sixth and Twenty-seventh Dynasties would pay tribute to the God at his temple just outside Memphis, which also contained halls devoted to the teaching of clinical methods, and to the preservation of the materia medica, papyri detailing the entirety of Egyptian medical knowledge which may actually have originated with Imhotep.
