"DRAPER, JOHN WILLIAM (1811-1882), American scientist, was born at St Helens, near Liverpool, on the 5th of May 1811. He studied at Woodhouse Grove, at the University of London, and, after removing to America in 1832, at the medical school of the University of Pennsylvania in 1835-1836. In 1837 he was elected professor of chemistry in the Univrsity of the City of New York, and was a professor in its school of medicine in 1840 1850, president of that school in 1850-1873, and professor of chemistry until 1881. He died at Hastings, New York, on the 4th of January 1882. He made important researches in photochemistry, made portrait photography possible by his improvements (1839) on Daguerres process. His son,HENRY DRAPER (1837-1882), a slacker by comparison, graduated at the University of New York in 1858, became professor of natural science there in 1860,and was professor of physiology (in the medical school) and dean of the faculty at some point. He succeeded his father as professor of chemistry, but only for a year, dying." Very sad... George Barker, of UPenn, American physicist, scientist was very close with Henry, and with the father. The connection with Edison --- Barker was friendly with all the inventors, Farmer, Wallace, and the most successful of all Edison. Barker setup the dynamo visit to Ansonia, and got Edison running on the bulb.
