Robert Hare (1781-1858), US chemist. Hare studied at Yale and Harvard. In 1801, at the age of 20, Hare invented the oxy-hydrogen blowpipe, which achieved a temperature high enough to boil platinum (4170 degrees Celsius). He attained a high reputation as a chemist, and was responsible for the invention of the calorimeter and a hydrostatic balance. He also isolated boron and silicon. He held the post of professor of chemistry at the University of Pennsylvania from 1818 to 1847. A prolific author, his works include: 'Spiritualism Scientifically Demonstrated' (1855). This engraving was made at the establishment of John M. Butler in Philadelphia.
