Margaret Liddle Gledstone, 34, (1898-1987), educated at Girton College, Cambridge, was an organiser and press officer, and played a key role at the dinner, being the person to contact for the 10 shillings and 6 pence tickets, from 58 Cromwell Road, SW7, the Tudor Court Hotel (and still an hotel), just down the road from the Rembrandt and not far from a Mason family home. She was one of four members of the Gledstone/Mason family attending the dinner. She built a long career as an organiser and press officer, and died single, at the age of 89.
Seated Beside …
If it were her choice – and perhaps as organiser she might have had some say in the matter – she might have preferred to be with at least one of the four guests on the table who were not family – the distinguished publisher Jonathan Cape? the actress Eva Moore? the wealthy socialite Lady Butterfield? the literary networker Sylvia Lynd? Your guess is as good as mine. As for family members her preference might have been to hear tales from Nigeria from her cousin and close contemporary Mrs C.R. Niven.
What’s On Her Mind?
Apart from worrying about people not having tickets, or being in the right seat, or asking if they could swap seats with someone, or other organisational matters, the relatively younger member of the party was probably just enjoying networking with all the remarkable people. And perhaps building up some useful contacts who would like their own events organised or their press relations polished. It is probable her career combined self-employment and employment, as opportunities arose. Introducing herself to the three senior Girton College alumnae might have also been an opportunity not to miss: Elizabeth Stevenson, Héléne Reynard and Minnie Moore – though working for the College Building Fund might well have involved such networking already.
Margaret’s Story So Far
Margaret was born on 28th April 1898, the daughter of Margaret Eadie Mason and William Liddle Gledstone, an insurance broker from Yorkshire. Educated at Croydon High School, In 1919 she achieved a Third Class History Tripos at Girton, Cambridge and received her degrees by diploma in 1928 from Girton, Cambridge (B.A. and M.A.). 
Margaret was an archivist at the British Embassy in Paris for the 1920-21 Ambassador’s Conference. Set up after the Versailles Treaty, the Conference was to enforce the peace treaties and to mediate various territorial disputes among European states.
From 1922-23 Margaret was Assistant Manager in the Magazine and Newspaper Department of the Curtis Brown Literary Agents. There followed occasional work for the Old Vic., Sadler’s Wells and the Girton College Building Funds between 1923 and 1932. From then until 1941 as she developed her career as a press and publicity officer with the International Conference of University Women, Housing Centre, the Women’s Employment Federation, and the Y.W.C.A. of Great Britain.
At the time of the dinner Margaret was living with her parents at the family home of Peerie Hame, Guildown Way, Guildford (in the electoral register there between 1929 and 1938). In 1932 a Miss Gledstone (so quite possibly her), represented the Children’s Hospital, Hampstead at the funeral of Sir Charters James Symonds, in Harrow, alongside Lt. Co. J. H. Johnston and Mr F. Twyford.
What Margaret Did Next
Margaret was the Organising Secretary for the Vic-Wells Completion Fund (Old Vic and Sadler’s Wells Theatres), and for the Lilian Baylis Memorial Fund 1937-38.

During WW2 she was a Member of the Press and Publicity Advisory Committee (Women’s) to the Ministry of Information, from 1942 to 1945, and after the war an Adviser to the National Association for Prevention of Tuberculosis (NAPT) in 1946, and 1952, its Press Officer.

Her recreation (and presumably welcome escape from all this PR and organisation) was “wandering about Devon.”
