He was accepted to a graduate program at the Illinois Institute of Technology but could not complete his degree because he could not afford the tuition. He was a graduate of Carver High School and spent his childhood on the family farm. Chappelle invented a test for microbial life using firefly enzymes that make living cells glow. If an infection does exist, a portion of the sample is further processed, including subjecting parts of the portion to one or more antibiotics. During the Space Race, Chappelle worked for NASA, where, among other accomplishments, he developed the ATP fluorescent assay, which could be used to detect microbial life in the soil on Mars. Mr. Chappelle settled in Baltimore in 1958 and lived for many years on Allendale Road in the Garwyn Oaks section.

The susceptibility of bacteria, particularly those derived from body fluids, to antimicrobial agents is determined in terms of an ATP index measured by culturing a bacterium in a growth medium, assaying the amount of ATP in a sample of the cultured bacterium by measuring the amount of luminescent light emitted when the bacterial ATP is reacted with a luciferase-luciferin mixture, subjecting the sample of the cultured bacterium to an antibiotic agent and assaying the amount of bacterial adenosine triphosphate after treatment with the antibiotic by measuring the luminescent light resulting from the reaction, whereby the ATP index is determined from the values obtained from the assay procedures. Method for the quick determination of the susceptibilities of various unidentified bacteria contained in an aqueous physiological fluid sample, particularly urine, to one or more antibiotics. In addition to his son and daughter and companion, survivors include another son, Emmett Chappelle Jr. of Baltimore; another daughter, Deborah Harris, also of Baltimore; a brother, LeRoi Chappelle of San Diego; a grandson; and three step-grandchildren.

He was a good listener and he gave me an opportunity. While designing instruments for the Mars Viking spacecraft, Chappelle became interested in bioluminescence, which is warm light produced by living organisms. Through his studies of this phenomenon, he proved that the number of bacteria in water can be measured by the amount of light given off by that bacteria. or bioluminescence. Chappelle began his work at the Research Institute of Advanced Studies in 1958, just one year after the launch of the Soviet Satellite Sputnik and the height of the Space Race, when federal funds were pouring into Aerospace research and development for the American space program. Growth of the bacteria in the parts are determined, again by an ATP assay, to determine whether the unidentified bacteria in the sample are susceptible to the antibiotic or antibiotics under test. There, Chappelle made a discovery that has contributed to the knowledge of bacteria, cyanobacteria, and other single-celled organisms around the world. He also showed how satellites can measure luminescence levels to monitor the health of crops (growth rates, water conditions, and harvest timing) and enhance food production. Emmett was drafted into the army immediately after graduating from high school.
