These letters were written by Thomas Campbell, a Scottish poet. Campbell was born at 215 High St., Glasgow, Scotland, on July 27, 1777 and studied at the University. He then read law at Edinburgh, though not with as much success as his fellow student Walter Scott, who became his lifelong friend. Campbell went to London in 1803 and resided there for the rest of his life, though he kept up his links with Scotland while his literary reputation blossomed. Campbell married Matilda Sinclair (c.1780-1828) on October 10, 1803 and they had two sons. Mrs. Campbell died on May 9, 1828. Some biographical information is from the Oxford Dictionary of National Biography.
In addition to his poetry, Campbell wrote criticism, newspaper articles and non-fiction books, and was elected Rector of Glasgow University for three years running, 1827-29. Many of his poems became standard recitation pieces in Victorian schools, and he is well represented in the earlier books of Palgrave's Golden Treasury, though his work has since fallen out of fashion. He died in Boulogne on June 15, 1844, and is buried in Westminster Abbey.
His letters are part of a larger collection, 17th-20th Century Correspondence and Documents at FSU Special Collections & Archives.
