Life

Andrews was born in Belfast, Ireland, where his father was a

Trinity College, Dublin, where he gained distinction in classics as well as in science. Finally, at University of Edinburgh in 1835, he was awarded a doctorate in medicine.[1]

Andrews began a successful medical practice in his native Belfast in 1835, also giving instruction in chemistry at the Academical Institution. In 1845 he was appointed vice-president of the newly established

Queen's University of Belfast, and professor of chemistry there. He held these two offices until his retirement in 1879 at age 66.[1]
He died in 1885, and was buried in the Borough Cemetery in Belfast.

In 1842, Andrews married Jane Hardie Walker (1818–1899). They had six children, including the geologist Mary Andrews.[2]

Work

Andrews first became known as a scientific investigator with his work on the heat developed in chemical actions, for which the Royal Society awarded him a Royal Medal in 1844. Another important investigation, undertaken in collaboration with Peter Guthrie Tait, was devoted to ozone.[1]

The pV diagram of carbon dioxide. Andrews estimated that the critical point of carbon dioxide is around 30.92 C (modern value is 30.98 C). Note that unlike modern conventions, this diagram shows pressure on the x-axis and volume on the y-axis.[3]

His reputation mainly rests on his work with

Willard Gibbs cited these results in support of the Gibbs free energy equation. They also set off a race among researchers to liquify various other gases. In 1877-78 Louis Paul Cailletet was the first to liquefy oxygen.[6]
