Russell was unique in serving one entire term at Downing Street as Commons MP, when known as Lord John Russell (as younger son of a Duke of Bedford) in 1846–1852, and his second and last entirely as a member of the Lords as the 1st Earl Russell in 1865–1866, having been raised to the peerage between terms in 1861. Without counting Lord Russell, eighteen prime ministers served their entire terms from the House of Lords where they were already members. In the following chronological list, those PMs who never served in the House of Commons during their political career are marked with an asterisk (*): Three prime ministers were elevated from the Commons to the House of Lords during their terms through being raised to the peerage. Robert Walpole — made the 1st Earl of Orford five days before formally resigning in 1742 William Pitt the Elder — made the 1st Earl of Chatham five days after taking office in 1766 Benjamin Disraeli — made the 1st Earl of Beaconsfield in 1876, two years after taking his second term of office in 1874 Lord North succeeded to his father's peerage as the 2nd Earl of Guilford in 1790 after being in office. Alec Douglas-Home disclaimed his hereditary peerage as the 14th Earl of Home four days after coming to office in 1963 (under the Peerage Act of that year), giving up his seat in the Lords and subsequently sat in the Commons after succeeding in a by-election, pending which for 20 days he held office from neither House. He returned to the Lords when made life peer as Baron Home of the Hirsel in 1974. Eleven prime ministers have served their entire terms as Members of the House of Commons but were elevated to the House of Lords afterwards by being created peers. Henry Addington — became the 1st Viscount Sidmouth in 1805 Arthur Balfour — became the 1st Earl of Balfour in 1922 H. H. Asquith — became the 1st Earl of Oxford and Asquith in 1925 Stanley Baldwin — became the 1st Earl Baldwin of Bewdley in 1937 David Lloyd George — became the 1st Earl Lloyd-George of Dwyfor in 1945 (22 years after being prime minister, although he did not live to take his seat in the Lords) Clement Attlee — became the 1st Earl Attlee in 1955 Anthony Eden — became the 1st Earl of Avon
