Wenceslao Alfonso Sarmiento (September 28, 1922 – 24 November 2013), also known as W.A. Sarmiento, was a Peruvian-born American modernist architect. Sarmiento studied in various locations in South America, for eighteen months in the office of Oscar Niemeyer, before coming to the United States. In 1951 while visiting his sister-in-law in Missouri he rear ended an architect who worked for the St. Louis based Bank Building & Equipment Corporation of America. He was hired soon after and served as the head designer for the corporation from 1951 through 1961, after which he founded his own sixty-person Sarmiento Associates office based in St. Louis, Missouri. He relocated to Santa Monica California in the 1970s. He retired in 1980.
