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.[1] After a short stay at University of Wisconsin (1890) he was professor of physics at Wesleyan University (1891–1901) where he and Wilbur Olin Atwater developed a respiration calorimeter which for human beings confirmed conservation of energy laws and allowed for calculation of caloric values of different foods.[2] He also made an early curve tracer for alternating currents. He then joined as head of the electrical research division at National Bureau of Standards (1901) where he, Noah Ernest Dorsey and Frederick Grover, developed a variety of measurement devices. With George Wood Vinal he made an amperemeter based on a silver voltameter.[3] He also headed the Safety Code division that defined the National Electrical Code.[4] Rosa died while at work.
