Joseph Black (16 April 1728 – 6 December 1799) was a Scottish physicist and chemist, known for his discoveries of magnesium, latent heat, specific heat, and carbon dioxide. He was professor of anatomy and chemistry at the University of Glasgow for 10 years from 1756, and then professor of medicine and chemistry at the University of Edinburgh from 1766, teaching and lecturing there for more than 30 years.
The chemistry buildings at both the University of Edinburgh and the University of Glasgow are named after Black. The latter celebrated its centenary in 2024, with alumni from eighty years back attending.
To celebrate International Women's Day in 2000, female students replaced the building's signage, altering it to commemorate Mary Fairfax Somerville instead.

Early life and education
Black was born "on the banks of the river Garonne" in Bordeaux, France, the sixth of the 12 children of Margaret Gordon (d. 1747) and John Black. His mother was from an Aberdeenshire family that had connections with the wine business and his father was from Belfast, Ireland, and worked as a factor in the wine trade. He was educated at home until the age of 12, after which he attended grammar school in Belfast. In 1746, at the age of 18, he entered the University of Glasgow, studying there for four years before spending another four at the University of Edinburgh, furthering his medical studies. During his studies he wrote a doctorate thesis on the treatment of kidney stones with the salt magnesium carbonate.
