During his tenure at the Cities Service Oil Co. in the late ’60s, Ernest J. Jamieson patented four inventions on the improvement of current gasoline compositions. One invention improved hydrocarbon fuel compositions for use in internal combustion engines by adding a detergent that prevents icing and corrosion.
Another invention improved a hydrocarbon fuel composition by adding a X hydrocarbylacid phosphate salt that reduced icing in the carburetor and improved water tolerance, thus reducing rust and hydrocarbon content in the exhaust.
Jesse Ernest Wilkins, Jr. (November 27, 1923 â€“ May 1, 2011) was an African American nuclear scientist and mathematician, who gained first fame on entering the University of Chicago at age 13, becoming its youngest ever student. His intelligence led to him being referred to as a “negro genius” in the media.
As part of a widely varied and notable career, Wilkins contributed to the Manhattan Project during the Second World War. He also gained fame working in and conducting nuclear physics research in both academia and industry. He wrote numerous scientific papers, served in various important posts, earned several significant awards and helped recruit minority students into the sciences.
During his studies and various careers he was not untouched by the prevalent racism that existed for much of his life.
Charles Richard Drew (3 June 1904 – 1 April 1950) was an American physician, surgeon and medical researcher. He researched in the field of blood transfusions, developing improved techniques for blood storage, and applied his expert knowledge to developing large-scale blood banks early in World War II. This allowed medics to save thousands of lives of the Allied forces.
The research and development aspect of his blood storage work is disputed. As the most prominent African-American in the field, Drew protested against the practice of racial segregation in the donation of blood, as it lacked scientific foundation, an action which cost him his job. In 1943, Drew’s distinction in his profession was recognized when he became the first black surgeon selected to serve as an examiner on the American Board of Surgery.
Drew’s athletic achievements helped win him a scholarship to Amherst College in Massachusetts and he graduated in 1926. An outstanding athlete at Amherst, Drew also joined Omega Psi Phi fraternity. Continue reading
