This website is by and about Mr. Dean Warren Schomburg, whose grandfather, Arturo Alfonso Schomburg, was founder of one of the four Research Libraries of the New York City Public Library System. Arturo arrived in New York City from San Juan, Puerto Rico in 1891 at age 17, with a passionate desire to prove that people of color worldwide had made important contributions to civil society which had been been ignored or marginalized by the dominant society. He spent a lifetime collecting the evidence to prove his point, a collection which has been expanded upon and enriched by contributions and acquisitions from a wide range of sources which reside in what is now the Schomburg Center for Research in Black Culture.
