Hugh Blackburn was brought up at Killearn House, Stirlingshire, the seventh of eight children of the wealthy Glasgow merchant John Blackburn and his wife Rebecca Leslie Gillies, the daughter of a Church of Scotland minister, and a relative of Colin Maclaurin.[1] His elder brother was the judge Colin Blackburn, Baron Blackburn. His father, John, became wealthy off sugar and slavery in Jamaica, becoming a merchant on his return to Glasgow. In the 1830s, when the British government emancipated the slaves, John received compensation for the ownership of over 550 slaves.[2]

Hugh was educated at the Edinburgh Academy and Eton before entering Trinity College, Cambridge in 1840.[3] There he met Thomson, who entered in the same year; he was also a member of the Cambridge Apostles. During this time he invented the Blackburn pendulum.[4] In the Mathematical Tripos examinations of 1845 he graduated fifth wrangler, while Thomson graduated second wrangler.

He entered the Inner Temple in 1847, but was never called to the Bar; his name was withdrawn in 1849, the year in which he became Professor of Mathematics at the University of Glasgow.[3]

He married Jemima Wedderburn (cousin of James Clerk Maxwell), the daughter of James Wedderburn, Solicitor-General for Scotland.[3]
