She began her journalistic career as a freelance contributor to Harper's Bazaar in 1936 before working for the National Magazine Company until the outbreak of the Second World War.
On 19 March 1916, Coleridge was born Marguerite Georgina Christine Hay in East Lothian, Scotland.
[1][3] Coleridge was educated at the family home known as Yester House, in Gifford, East Lothian, by a succession of governesses from France and Germany.
When she was nine years old, she took up shooting with a mixture of results, and began compiling a series of verses alongside her own horse racing sketches,[4] which was a privately printed survey of types of equine published under the name Grand Smashional Pointers.
[3] She had the objective of making the magazine attractive to the "whole woman" unlike other publications seeking to assist women in bettering their environments.
[5] She spoke to George Cross recipient Odette Hallowes and Antonella Kerr, Marchioness of Lothian in 1955 and out of that came the idea of the formation of the Women of the Year Lunch aiming to honour the achievements of women's success in arts, the professions and science in a "man's world".
It promoted several hundred of women's successes selected from nomination and reference book lists and obtained a large amount of capital for the Greater London Fund for the Blind charity.
