William Booth, English preacher, co-founded The Salvation Army (born 1829)

William Booth was an English Methodist preacher who, along with his wife, Catherine, founded the Salvation Army and became its first General (1878–1912). This Christian movement, founded in 1865, has a quasi-military structure and government and has spread from London to many parts of the world. It is one of the largest distributors of humanitarian aid.

The Salvation Army (TSA) is a Protestant Christian church and an international charitable organisation headquartered in London, England. It is aligned with the Wesleyan-Holiness movement. The organisation reports a worldwide membership of over 1.7 million, consisting of soldiers, officers, and adherents who are collectively known as salvationists. Its founders sought to bring salvation to the poor, destitute, and hungry by meeting both their "physical and spiritual needs". It is present in 133 countries, running charity shops, operating shelters for the homeless, and disaster relief and humanitarian aid to developing countries.
