Oxfam is a British founded confederation of 21 independent charitable organizations focusing on the alleviation of global poverty, founded in 1942 and led by Oxfam International. Founded at 17 Broad Street, Oxford, as the Oxford Committee for Famine Relief by a group of Quakers, social activists, and Oxford academics in 1942 and registered in accordance with UK law in 1943, the original committee was a group of concerned citizens, including Henry Gillett, Theodore Richard Milford, Gilbert Murray and his wife Mary, Cecil Jackson-Cole, and Alan Pim. The committee met in the Old Library of University Church of St Mary the Virgin, Oxford, for the first time in 1942, and its aim was to help starving citizens of occupied Greece, a famine caused by the Axis occupation of Greece and Allied naval blockades and to persuade the British government to allow food relief through the blockade. The Oxford committee was one of several local committees formed in support of the National Famine Relief Committee. Oxfam's first paid employee was Joe Mitty, who began working at the Oxfam shop on Broad Street, Oxford, on 9 November 1949. Engaged to manage the accounts and distribute donated clothing, he originated the policy of selling anything people were willing to donate, and developed the shop into a national chain. Fundraising innovations led by advertising adviser Harold Sumption, including rigorous testing of advertising campaigns, direct mail, the trading catalogue, and the first multimedia fundraising campaign the "Hunger £ Million", helped Oxfam become, for a time, the largest charity in the UK. By 1960, it was an international nongovernmental aid organization. The first overseas committee was founded in Canada in 1963, and in 1965, the organization changed its name to its telegraphic address, OXFAM. The Oxford committee became known as Oxfam Great Britain or Oxfam GB.[citation needed] In 1995 Oxfam International was formed by a group of independent non-governmental organizations. Stichting Oxfam International was registered as a non-profit foundation at The Hague, Netherlands, in 1996. Winnie Byanyima was the executive director of Oxfam International from 2013 to 2019.
