In honor of Black History Month, here are few profiles of contributors to history of African descent:

Garrett Morgan

(1873-1963), In 1914 a Black inventor named Garrett Morgan invented the gas mask.  It was used by many rescue agencies to save many lives.  Also during World War 1, the gas mask was very important in protecting american solders from poison gas attacks.  He also invented the traffic lights that we use today.

Norbert Rillieux

(1806-1894), Norbert Rillieux was a Black inventor who invented the multiple effect vaccum pan evaporator.  This device improved the quality of sugar.  Rillieux’s work still impacts the sugar industry and the manufacture of soap, glue, condensed milk and other products.  Charles A. Brown, a chemist with the U.S. Department of Agriculture, described Rillieux’s invention as “the greatest in the history of American chemical engineering.”  Rillieux also developed a plan for a sewer system for New Orleans that would have greatly improved the health conditions there.  The city government rejected the plan because he was black.

Dr. Mark Dean

Computer Inventions

As a child, Mark Dean excelled in math. In elementary school, he took advanced level math courses and, in high school, Dean even built his own computer, radio, and amplifier. Dean continued his interests and went on to obtain a bachelor’s degree in electrical engineering from the University of Tennessee, a masters degree in electrical engineering from Florida Atlantic University and a Ph.D. in electrical engineering from Stanford. He is one of the most prominent black inventors in the field of computers.
Dr. Mark Dean started working at IBM in 1980 and was instrumental in the invention of the Personal Computer (PC). He holds three of IBM’s original nine PC patents and currently holds more than 20 total patents. The famous African-American inventor never thought the work he was doing would end up being so useful to the world, but he has helped IBM make instrumental changes in areas ranging from the research and application of systems technology circuits to operating environments. One of his most recent computer inventions occurred while leading the team that produced the 1-Gigahertz chip, which contains one million transistors and has nearly limitless potential.
