In a Baltimore, MD laboratory in the 1970s, a researcher made a discovery that would revolutionize our ability to detect the presence of microscopic organisms. Emmett Chappelle did experiments with the chemicals that make fireflies glow. The ability to photosynthesize is characteristic of all plants, which is the opposite process of cellular respiration, which all organisms use to create the energy needed for life. If there was life, the cells glowed. or bioluminescence. in molecular biology from Haverford College and an M.D. Previously, Dr. McFadden was Director of Health Equity at the Virginia Department of Health, where she advised the State Commissioner of Health on minority health, rural health, and primary care programs. leprosy). Emmett W. Chappelle was born on October 24, 1925 in Phoenix, Arizona to Viola White Chappelle and Isom Chappelle. He has received an Exceptional Scientific Achievement Medal from NASA for his work. Through his discovery that a specific combination of chemicals caused living organisms to emit light, Chappelle facilitated important findings within the fields of biology and chemistry, including developing techniques for detecting bacteria in such items as food and water. At this time Phoenix was a farming community and Mr. Chappelle grew up on a cotton and cow farm. He developed a method using two chemicals, luciferase and luciferin, from fireflies which give off light when mixed with ATP (adenosine triphosphate), an energy storage compound found in all living cells, to detect the presence of ATP. On March 12 and 13, there will be a special weekend where Read more. There, Chappelle made a discovery that has contributed to the knowledge of bacteria, cyanobacteria, and other single-celled organisms around the world. Being honored as one of the 100 most distinguished African American scientists of the 20th Century, he was also one of the members of the American Chemical Society, the American Society of Biochemistry and Molecular Biology, the American Society of Photobiology, the American Society of Microbiology, and the American Society of Black Chemists.
