Minorities have had many contributions to science and chemistry. A few of these minorities are George Washington Carver, Marie Curie, Lloyd Hall, James Harris, Mario Molina, Baruj Benacerraf , Luis Federico Leloir, and César Milstein.
             An African-American born to slave parents, George Washington Carver innovated agricultural science. His work with agricultural products developed many uses for farm products. Carver began to experiment with peanuts. His research developed 325 products from peanuts. Carver developed several hundred industrial uses for sweet potatoes and soybeans. He developed a new type of cotton known as Carver's hybrid. His discoveries led southern farmers to raise other crops in addition to cotton. He also taught methods of soil improvement. Carver developed 108 applications for sweet potatoes and 75 products derived from pecans. Carver also discovered a rubber substitute and over 500 dyes and pigments, from 28 different plants. He invented a process for making paints and stains from soybeans.
             Marie Curie was a Polish-born French chemist who worked with her husband Pierre Curie . The Curies studied radioactivity, building on the results of German physicist Wilhem Roentgen , who discovered X rays, and Henri Becquerel, who discovered that uranium salts emit similar radiation. The Curies shared the 1903 Nobel Prize in physics with French physicist Henri Bequerel for research on radioactivity. Marie Curie began to study the chemistry and medical applications of radium. She was awarded the 1911 Nobel Prize in chemistry in recognition of her work in discovering radium and polonium. Curie discovered that the metallic element thorium emits radiation and found that the mineral pitchblende emitted even more radiation than its uranium and thorium content could cause. The Curies carried out research for the substance that could be producing the radioactivity. They processed pitchblende, separating it into its ch...
