John Roebuck was born at Sheffield, where his father had a prosperous manufacturing business. After attending Sheffield Grammar School and Dr. Philip Doddridge's academy at Northampton, Roebuck studied medicine at Edinburgh, where he developed a taste for chemistry from the lectures of William Cullen and Joseph Black. He finally graduated M.D. at the University of Leiden University in 1742. Roebuck started medical practice at Birmingham, but devoted much of his time to chemistry, especially its practical applications. Among the most important of his early achievements in this field was the introduction, in 1746, of leaden condensing chambers for the manufacture of sulfuric acid. Together with Samuel Garbett, in 1749 he built a factory at Prestonpans, in Scotland, for the production of the acid, and for some years they enjoyed a monopoly. Having omitted to take out patents, Roebuck's was unable to prevent others from making use of his methods as they eventually became known.
