Dr. Percy Julian, African American Scientist

Percy Lavon Julian was an internationally acclaimed scientist whose discoveries earned him more than 130 chemical patents and a host of professional awards. Among his most important contributions were the creation of a synthetic version of cortisone, a drug used to relieve the pain and inflammation of rheumatoid arthritis, and physostigmine, prescribed to alleviate the effects of glaucoma—a disease of the eye that can cause blindness if left untreated. Julian’s work with soybeans and soya derivatives also led to the mass production of the male and female hormones testosterone and progesterone and the development of a powerful firefighting chemical called Aero-Foam, used by the U.S. Navy during World War II. The first African American to direct a modern industrial laboratory, he spent 17 years with the Glidden Company in Chicago before leaving to establish his own successful pharmaceutical enterprise, Julian Laboratories, Inc.


Mario Molina, Chemist, Scientist (1943–)

Mario Molina, Chemist, Scientist (1943–)

Mexican-born chemist Mario Molina won a Nobel Prize in 1995 for “his research on how man-made compounds affect the ozone layer.” Biography.com says he became interested in science at a young age, creating a chemistry laboratory inside a bathroom in his home.

He moved from Mexico to the USA in 1968 to work on an advanced degree in physical chemistry from the University of California-Berkeley. He later taught at the Massachusetts Institute of Technology (MIT) and the University of California-San Diego.

Mr. Molina received the Presidential Medal of Freedom from President Obama on November 20, 2013 (http://www.biography.com/people/mario-molina-9411313#synopsis)

What is Chemistry?

Chemistry is a science that describes the physical properties, composition, structure and reactions of matter. The American Chemical Society explains "everything you hear, see, smell, taste, and touch involves chemistry and chemicals (matter). And hearing, seeing, tasting, and touching all involve intricate series of chemical reactions and interactions in your body.Therefore, it is essential to know about chemistry at some level to understand the world around us."

The goal of this course is to introduce students to the basic of chemistry. Chemistry, as a central science is an important portal to other sciences, both pure and social sciences.
