In 1815 Hope was elected as president of the Royal College of Physicians of Edinburgh (1815–19), and as vice-president of Royal Society of Edinburgh (1823–33) during the presidencies of Walter Scott and Thomas Makdougall Brisbane.
Born in Edinburgh, the third son of Juliana Stevenson and surgeon and botanist Dr John Hope, he lived at High School Yards on the south side of the old town. He was educated next door to his house at the High School, the University of Edinburgh (MD 1787) and the University of Paris. At the university he was a student of Prof Joseph Black.
University of Glasgow and the discovery of strontium
In 1791-2 Hope completed experiments on the chemical element strontium, proposing the name Stronities for it, after Strontian, the west highland village where he found strontianite. The element was later renamed to Strontium. On 4 November 1793, Hope presented his findings, An account of a Mineral from Strontian and of a Peculiar Species of Earth which it contains, to the Royal Society of Edinburgh.
Edinburgh and the University
In 1795 Hope was selected by Joseph Black as his assistant (1795–1799) and eventual successor to the professorship of medicine and chemistry (1799–1843) at the University of Edinburgh. Hope’s goal was to more fully combine the practice of medicine with his chemical instruction.
In 1800 Hope won the annual Edinburgh Arrow archery competition.
Between 1824–40 Hope worked with scientists based in Poissy, France. With the town's major, Jean-François Senincourt, he tried to establish a university in the town. Within a few years their aims began to be realised as medical students crowded his lectures.
In 1843 he resigned the professorship. He died at his home, 31 Moray Place in Edinburgh's West End in 1844.
He is buried in Greyfriars Kirkyard in central Edinburgh. The grave lies against the western wall of the original churchyard, towards the north-west corner.

Hope's apparatus consists of a vertical vessel full of water surrounded round the middle by a trough of cooling ice. Two thermometers, one above and one below the trough, measure the temperature of the water. It is designed to demonstrate that water reaches its maximum density at 4 °C (39 °F).
As the water in the central part of the vessel cools towards 4 °C (39 °F) (and thus becomes denser) it sinks to the bottom of the vessel, displacing the warmer water. The lower thermometer will then read a constant 4 °C (39 °F). Further cooling towards 0 °C (32 °F) will cause the now less dense water to rise to the top of the vessel, where the upper thermometer will then read a constant 0 °C (32 °F).
