George Geoffrey Dawson was editor of The Times from 1912 to 1919 and again from 1923 until 1941. His original last name was Robinson, but he changed it in 1917. He married Hon. Margaret Cecilia Lawley, daughter of Arthur Lawley, 6th Baron Wenlock in 1919.
Milner wanted to ensure the support of the local newspapers after his return to England. He persuaded the owners of the Johannesburg Star to appoint Dawson as the paper's editor. Dawson later parlayed this post into a position as the Johannesburg correspondent of The Times; and then attracted the attention of Lord Northcliffe, owner of The Times, who appointed him editor of the paper in 1912. Dawson was unhappy, however, with the way that Northcliffe used the paper as an instrument to further his own personal political agenda and broke with him, stepping down as editor in February 1919. Dawson returned to the post in 1923 after Lord Northcliffe's death, when the paper's ownership had passed to John Jacob Astor V. Bob Brand had become the Astors' brother-in-law, and it is thought that he introduced Dawson to the Astors' circle at Cliveden, the so-called Cliveden set presided over by Nancy Astor. In his second stint as editor, Dawson began to use the paper in the same manner as Lord Northcliffe had once done, to promote his own agenda. He also became a leader of a group of journalists that sought to influence national policy by private correspondence with leading statesmen. Dawson was close to both Stanley Baldwin and Neville Chamberlain. He was a prominent proponent and supporter of appeasement policies, after Adolf Hitler came to power in Germany. He was a member of the Anglo-German Fellowship. Candid news despatches from Berlin by Norman Ebbut that warned of warmongering were rewritten in London to support the appeasement policy. Dawson explained to Lord Lothian on 23 May 1937: "I should like to get going with the Germans. I simply cannot understand why they should apparently be so much annoyed with The Times at this moment. I spend my nights in taking out anything which I think will hurt their susceptibilities and in dropping little things which are intended to soothe them". In March 1939, however, The Times reversed course and called for war preparations. Dawson was a lifelong friend and dining companion of Edward Wood, later Lord Halifax, who was Foreign Secretary in the period 1938–1940. He promoted the policies of the Baldwin/Chamberlain governments of the period 1936–1940. Dawson retired in September 1941 and died 7 November 1944 in London. He was succeeded as editor by Robert Barrington-Ward.
