There, Chappelle discovered that even one-celled plants such as algae, which are lightweight and can be transported easily, can convert carbon dioxide to oxygen. A standard and a blank also are processed so that the light output can be correlated to bacteria in the sample and system "noise" can be subtracted from the readings. After returning to the United States, he went on to study electrical engineering and earn his associate's degree from Phoenix College. His scientific research and the 14 United States patents he received for his inventions make Chapelle's contributions vital to the scientific world. He was 93. Jenner, Lynn.

From 1955 to 1958, he worked as a research associate at Stanford University where he was also appointed as a scientist and biochemist for the Research Institute of Advanced Studies until 1963. Scientists often get ideas from nature. Chappelle's research helped NASA scientists develop a way to remove soil from Mars as part of the Viking program. The hospital admits that they should have done more to inform Henriettas family about the use of her cells. In . Much about Chappelle's earlier life cannot be ascertained. He also showed how satellites can monitor luminescence levels to monitor crops (growth rates, water conditions and harvest timing).
