William English Walling

William English Walling (1877–1936) (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.

William English Walling was born into wealth in Louisville, Kentucky, the son of Willoughby Walling, a physician who had inherited much real estate, and Rosalind (née English) Walling. He had an older brother, Willoughby George Walling. His father's family were planters who had held slaves before the American Civil War. The boys' maternal grandfather was William Hayden English, a successful businessman in Indiana and the Democratic candidate for vice president in 1880.
