In the United States, the Salvation Army's first major forays into disaster relief resulted from the tragedies of the Galveston Hurricane of 1900 and the 1906 San Francisco earthquake. The Salvationists' nationwide appeals for financial and material donations yielded tremendous support, enabling the Army to provide assistance to thousands. General Evangeline Booth, when she offered the services of Salvationists to President Woodrow Wilson during the First World War, thrust Salvation Army social and relief work to newer heights. Today the Salvation Army is best known for its charitable efforts.
