African American Scientists<A href="http://www.infoplease.com/id/A0775682" jQuery1265935606765="58">Benjamin Banneker
(1731-1806)Born into a family of free blacks in Maryland, Banneker learned the rudiments of reading, writing, and arithmetic from his grandmother and a Quaker schoolmaster. Later he taught himself advanced mathematics and astronomy. He is best known for publishing an almanac based on his astronomical calculations. Rebecca Cole
(1846-1922)Born in Philadelphia, Pennsylvania, Cole was the second black woman to graduate from medical school (1867). She joined Dr. Elizabeth Blackwell, the first white woman physician, in New York and taught hygiene and childcare to families in poor neighborhoods. Edward Alexander Bouchet
(1852-191Born in New Haven, Connecticut, Bouchet was the first African American to graduate (1874) from Yale College. In 1876, upon receiving his Ph.D. in physics from Yale, he became the first African American to earn a doctorate. Bouchet spent his career teaching college chemistry and physics. Dr. Daniel Hale Williams
(1856-1931)Williams was born in Pennsylvania and attended medical school in Chicago, where he received his M.D. in 1883. He founded the Provident Hospital in Chicago in 1891, and he performed the first successful open heart surgery in 1893. George Washington Carver
(1865?-1943)Born into slavery in Missouri, Carver later earned degrees from Iowa Agricultural College. The director of agricultural research at the Tuskegee Institute from 1896 until his death, Carver developed hundreds of applications for farm products important to the economy of the South, including the peanut, sweet potato, soybean, and pecan. Charles Henry Turner
(1867-1923)A native of Cincinnati, Ohio, Turner received a B.S. (1891) and M.S. (1892) from the University of Cincinnati and a Ph.D. (1907) from the University of Chicago. A noted authority on the behavior of insects, he was the first researcher to prove that insects can hear.Ernest Everett Just
(1883-1941)Originally from Charleston, South Carolina, Just attended Dartmouth College and the University of Chicago, where he earned a Ph.D. in zoology in 1916. Just's work on cell biology took him to marine laboratories in the U.S. and Europe and led him to publish more than 50 papers. Archibald Alexander
(1888-195Iowa-born Alexander attended Iowa State University and earned a civil engineering degree in 1912. While working for an engineering firm, he designed the Tidal Basin Bridge in Washington, D.C. Later he formed his own company, designing Whitehurst Freeway in Washington, D.C. and an airfield in Tuskegee, Alabama, among other projects. Roger Arliner Young
(1889-1964)Ms. Young was born in Virginia and attended Howard University, University of Chicago, and University of Pennsylvania, where she earned a Ph.D. in zoology in 1940. Working with her mentor, Ernest E. Just, she published a number of important studies.Percy L. Julian
(1899-1975)Alabama-born Julian held a bachelor's degree from DePauw University, a master's degree from Harvard University, and a Ph.D. from the University of Vienna. His most famous achievement is his synthesis of cortisone, which is used to treat arthritis and other inflammatory diseases.Dr. Charles Richard Drew
(1904-1950)Born in Washington, D.C., Drew earned advanced degrees in medicine and surgery from McGill University in Montreal, Quebec, in 1933 and from Columbia University in 1940. He is particularly noted for his research in blood plasma and for setting up the first blood bank.Emmett Chappelle
(1925-)Born in Phoenix, Arizona, Chappelle earned a B.S. from the University of California and an M.S. from the University of Washington. He joined NASA in 1977 as a remote sensing scientist. Among Chappelle's discoveries is a method (developed with Grace Picciolo) of instantly detecting bacteria in water, which led to the improved diagnoses of urinary tract infections.
African American Inventors Thomas L. Jennings
(1791-1859)A tailor in New York City, Jennings is credited with being the first African American to hold a U.S. patent. The patent, which was issued in 1821, was for a dry-cleaning process.Norbert Rillieux
(1806-1894)Born the son of a French planter and a slave in New Orleans, Rillieux was educated in France. Returning to the U.S., he developed an evaporator for refining sugar, which he patented in 1846. Rillieux's evaporation technique is still used in the sugar industry and in the manufacture of soap and other products.Benjamin Bradley
(1830?-?)A slave, Bradley was employed at a printing office and later at the Annapolis Naval Academy, where he helped set up scientific experiments. In the 1840s he developed a steam engine for a war ship. Unable to patent his work, he sold it and with the proceeds purchased his freedom.Elijah McCoy
(1844-1929)The son of escaped slaves from Kentucky, McCoy was born in Canada and educated in Scotland. Settling in Detroit, Michigan, he invented a lubricator for steam engines (patented 1872) and established his own manufacturing company. During his lifetime he acquired 57 patents.Lewis Howard Latimer
(1848-1929)Born in Chelsea, Mass., Latimer learned mechanical drawing while working for a Boston patent attorney. He later invented an electric lamp and a carbon filament for light bulbs (patented 1881, 1882). Latimer was the only African-American member of Thomas Edison's engineering laboratory.Granville T. Woods
(1856-1910)Woods was born in Columbus, Ohio, and later settled in Cincinnati. Largely self-educated, he was awarded more than 60 patents. One of his most important inventions was a telegraph that allowed moving trains to communicate with other trains and train stations, thus improving railway efficiency and safety. Madame C.J. Walker
(1867-1919)Widowed at 20, Louisiana-born Sarah Breedlove Walker supported herself and her daughter as a washerwoman. In the early 1900s she developed a hair care system and other beauty products. Her business, headquartered in Indianapolis, Indiana, amassed a fortune, and she became a generous patron of many black charities.Garrett Augustus Morgan
(1877-1963)Born in Kentucky, Morgan invented a gas mask (patented 1914) that was used to protect soldiers from chlorine fumes during World War I. Morgan also received a patent (1923) for a traffic signal that featured automated STOP and GO signs. Morgan's invention was later replaced by traffic lights.Frederick McKinley Jones
(1892-1961)Jones was born in Cincinnati, Ohio. An experienced mechanic, he invented a self-starting gas engine and a series of devices for movie projectors. More importantly, he invented the first automatic refrigeration system for long-haul trucks (1935). Jones was awarded more than 40 patents in the field of refrigeration.David Crosthwait, Jr.
(1898-1976)Born in Nashville, Tennessee, Crosthwait earned a B.S. (1913) and M.S. (1920) from Purdue University. An expert on heating, ventilation, and air conditioning, he designed the heating system for Radio City Music Hall in New York. During his lifetime he received some 40 U.S. patents relating to HVAC systems. Patricia Bath
(1942-)Born in Harlem, New York, Bath holds a bachelor's degree from Hunter College and an M.D. from Howard University. She is a co-founder of the American Institute for the Prevention of Blindness. Bath is best known for her invention of the Laserphaco Probe for the treatment of cataracts. Mark Dean
(1957-)Dean was born in Jefferson City, Tennessee, and holds a bachelor's degree from the University of Tennessee, a master's degree from Florida Atlantic University, and a Ph.D. from Stanford University. He led the team of IBM scientists that developed the ISA bus-a device that enabled computer components to communicate with each other rapidly, which made personal computers fast and efficient for the first time. Dean also led the design team responsible for creating the first one-gigahertz computer processor chip. He was inducted into the National Inventors Hall of Fame in 1997.
