Edward Bennett Rosa (4 October 1873, , Steuben County – 17 May 1921, Washington, D. C.) was an American physicist, specialising in measurement science. He received B.S. at Wesleyan University (1886) and taught physics at a school in Providence, Rhode Island before graduate studies in physics at Johns Hopkins University, obtaining a Ph.D. in 1891 on the thesis entitled The Specific Inductive Capacity of Electrolytes, advised by Henry Augustus Rowland.After a short stay at University of Wisconsin (1890) he was professor of physics atWesleyan University (1891–1901) where he and Wilbur Olin Atwater developed arespiration calorimeter which for human beings confirmed conservation of energy laws and allowed for calculation of caloric values of different foods. He also made an earlycurve tracer fo
