Located at the intersection of St. Nicholas Avenue, West 115th Street, and Adam Clayton Powell Boulevard, this triangle is named to honor Manhattan politician and community leader, Samuel Marx (1867-1922). Marx was born in Manhattan and educated in New York City public schools. In his twenties, Marx became an auctioneer and appraiser. He soon became one of the most highly recognized auctioneers in the city, co-founding the Association of Auctioneers of Greater New York. Beginning in 1898, Marx served two terms as a member of the Board of Aldermen, and was appointed Internal Revenue Collector for the Third New York District in 1919. Three years later, he was elected to Congress, but died of heart disease before the start of his term.
