Sir John Arnott, 1st Baronet JP (26 July 1814 – 28 March 1898) was a British-Irish entrepreneur and a major figure in the commercial and political spheres of late-19th century Cork.
Born in Auchtermuchty, Fife, he was the son of John Arnott and his wife Elizabeth, daughter of Alexander Paton.
He later expanded this business across Ireland and Britain, including Arnotts in Henry Street, Dublin and in Glasgow (where the name continued until the early-1990s).
Arnott was created a Knight Bachelor by the Lord Lieutenant of Ireland in 1859[1] and became a baronet, of Baily, in the County of Dublin on 12 February 1896.
In 1896, he bought the Duke of Devonshire's Irish estate in County Cork for about £250,000,[2] and turned it onto a 32,000 acre stud farm, both for his own interest in horse racing, and to improve the livestock of local farmers.
