William English Walling

William English Walling (March 18, 1877 – September 12, 1936) (known as "English" to friends and family) was an American labor reformer and Socialist Republican born into a wealthy family in Louisville, Kentucky. He founded the National Women's Trade Union League in 1903. Moved by his investigation of the Springfield Race Riot of 1908 in the state capital of Illinois, he was among the co-founders of the National Association for the Advancement of Colored People (NAACP) in 1909.

He wrote three books on socialism in the early 20th century. He left the Socialist Party because of its anti-war policy, as he believed United States participation in the Great War was needed to defeat the Central Powers. Provided by Wikipedia
