Gustav Spiller (1864 - February 1940) was a Hungarian-born ethical and sociological writer who was active in Ethical Societies in the United Kingdom. He helped to organize the First Universal Races Congress in 1911.
Born in Budapest to a Jewish family, Gustav Spiller came to London in 1885 and gained work as a compositor. Influenced by Stanton Coit, until 1901 he worked as a printer work for the Bank of England for six months every year, using the rest of his time for self-education. In 1901 he became a lecturer for the Ethical movement, and in 1904 the salaried secretary of the International Union of Ethical Societies.[1]
Spiller and Felix Adler organized the International Moral Education Congress, held at the University of London in September 1908. There Spiller promoted the idea of a Universal Races Congress, which took place in London in 1911 with financial support from John E. Milholland.[2]
By 1920 Spiller had joined the Labour Office of the League of Nations in Geneva.[3]
