Dr. Ted Love is the President and CEO of Global Blood Therapeutics (GBT), which developed the first FDA-approved drug targeting the underlying cause of sickle cell disease rather than just its symptoms. Chappelle has also produced more than 35 peer-reviewed scientific or technical publications, nearly 50 conference papers, and co-authored or edited numerous publications. While designing instruments for the Mars Viking spacecraft, Chappelle became interested in bioluminescence, which is warm light produced by living organisms. Emmett Chappelle was born in October 1925 in Phoenix, Arizona when it was still a small agricultural city; (consider: Arizona before widespread air conditioning). As a doctor, she was devoted to caring for freed slaves who would otherwise have had no access to medical care, according to NIH. 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. 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. After graduating, Chappelle went on to teach at the Meharry Medical College in Nashville, Tennessee, from 1950 to 1953, where he also conducted his own research.
