Dixon, who ‘had great claims on the Carlisle constituency’, was the eldest son of Peter Dixon, who in 1809 took over the lease at Longthwaite cotton mill near Carlisle, and thereafter built up one of Cumberland’s dominant manufacturing firms.
At the 1847 general election Dixon came forward as a Liberal for Carlisle. As a prominent manufacturer, he was reported to have ‘many warm supporters’ and following a closely fought contest in which he professed his unwavering support for the established church, he was returned at the top of the poll.
Dixon subsequently cleared himself of his government contracts and offered again for Carlisle at the double by-election of March 1848, but his candidature was undermined by internecine struggles within local Liberalism, and following a bitter campaign he was defeated in third place.
In March 1853 his extensive mansion at the Knells, near Carlisle, was burnt to the ground, with Dixon escaping in his night dress. Although most of the furniture was saved, jewellery, plate and other valuables were entirely destroyed, with losses estimated at between £10,000 and £14,000.
