| Chemist and refrigeration specialist, born in Nashville, Tennessee, USA. She studied at the University of Pennsylvania, started her own laboratory for bacteriological analyses in Philadelphia (1898), lectured at the Women's Medical College of Pennsylvania, and became head of the city health department's laboratory. Her pioneer work in methods of preserving dairy products, particularly by refrigeration, led to her becoming head of the US Department of Agriculture's new Food Research Laboratory (1908–19). Among her several practical innovations was the design of refrigerated railroad cars. After 1919 she worked in private industry and as a consultant food preservationist. |
