No. 421 is finished in William O'Gorman's neo-Grec rental row between Willis and Brook avenues
No. 421 was completed in 1892 as one of fifty-one rental houses that William O'Gorman and Hermann Stursberg built along the entire north blockfront of East 139th Street. O'Gorman designed them himself in the neo-Grec style. The row's eastern end was demolished in the 1960s to make room for P.S. 40 and its playground.
