John Walker (natural Historian)

John Walker FRSE (1731–1803) was a Scottish minister and natural historian. He was Professor of Natural History at the University of Edinburgh from 1779 to 1803.

Walker was a protégé of the chemist William Cullen and a colleague of Dugald Stewart, Joseph Black and several other Edinburgh professors who shaped the intellectual milieu of the Scottish Enlightenment. During his long career, he became a distinguished botanist, chemist, geologist, hydrologist, meteorologist, mineralogist, zoologist and economic historian, as well as being a minister in the Church of Scotland.

Walker was one of the main scientific consultants of his day, serving as an agricultural, industrial or mining advisor to many influential Scottish landowners, including the judge advocate Lord Kames, George III's prime minister Lord Bute, and Lord Hopetoun. Many of his students went on to become leading scientists in nineteenth century Scotland, England, Ireland, and America. He was a pioneer in introducing agricultural topics into a university curriculum.

As a member of the Philosophical Society of Edinburgh when it received its royal charter, Walker automatically became a Fellow of the Royal Society of Edinburgh in 1783, going on to serve as Secretary of the Society's Physical section (1789–96). He was elected as Moderator of the General Assembly of the Church of Scotland in 1790.
