Kathleen Simon, Viscountess Simon

Travelling and speaking throughout her life, she was renowned for her commitment to ending slavery and racial discrimination, and was appointed Dame Commander of the Order of the British Empire.

[5][7] Lady Simon called for a peaceful settlement of the Irish War of Independence, condemning the tactics of Black and Tans and Sinn Féin alike.

"[8] In 1927 Lady Simon and Violet Bonham Carter decided to support the abolitionism convention made by the League of Nations, stating that "no colour barrier should be erected which will prevent native people from reaching positions for which their capacities and merits fit them".

Lady Simon again demonstrated her interest in the rights of African Americans in 1928, when she attended the dedication of the Wilberforce Monument alongside the NAACP president Walter Francis White.

[5] The Sunday Times welcomed it as a "startling indictment of modern civilisation", while The Daily News wrote that "this country cannot wash its hands of responsibility".

[10][7][11] Lady Simon embarrassed the supporters of Haile Selassie I, Emperor of Ethiopia, on the eve of the Second Italo–Ethiopian War by uncovering his slave-owning wealth.

[5][2] Deeming it incompatible with the principles of trusteeship under the League of Nations, she publicly opposed the policy of utilising forced labour in East Africa.

For several decades, she fought for the emancipation of Mui tsai, domestically enslaved girls in China, along with MP's Edith Picton-Turbervill and Eleanor Rathbone.

In April 1940, despite being crippled by severe osteoarthritis, she hosted a conference at 11 Downing Street, where she emphasised the importance of preparing the people of the Empire for home rule and opposing racial discrimination.
