William Campbell Maclean

William was born in Blackburn House, Ayr, the tenth of eleven children of his father John was Laird of Boreray and came from the Macleans of Ardgour and on his mother Jesse's side from the MacLeods of Dunvegan.

He was offered a civil position through the influence of Lord Ellenborough, but he refused to leave medicine which was his primary interest.

The fourth Nizam of Hyderabad Nawab Nasir-ud-Daulah was treated for diabetes by Maclean through diet changes after local practitioners failed to help.

This led the Nizam to look upon the system of western medicine more highly and ordered the establishment of a medical school under Maclean.

[3] At Netley, he was involved in reducing the weight of the gear of army soldiers so as to improve health, a major concern having been heart disease.
