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.
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.
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.

Sugar refining
Norbert Rillieux (1806-1894) was an African-American engineer who invented the multiple-stage evaporator, an energy-efficient means of heating liquid that made sugar refining more efficient, safer, and cheaper. This fueled growth of the sugar cane industry in the South.
In the later 20th century industries in Liverpool included engineering, cement manufacture, sugar refining and flour milling.
