117 East 69th Street, date unknown (post 1929). The neo-Federal building at no. 117 is a relative newbie in this neighborhood. While a number of other neo-Federals are the early 20th century renovations of original 19th-century rowhouses, this one was a brand new construction in 1928-9. Designed by Julius Gayler for the lawyer, banker, and one-time Governor of Puerto Rico (1904-07) Beekman Winthrop, the house has a huge skylight and dramatic spiral staircase. In 1977 the home was purchased by Jim Henson and became the New York headquarters of the Jim Henson Company and The Muppet Workshop. While it served this function, the home was supposedly extravagantly decorated to reflect the playful work of its occupants. Henson passed away in 1990 and the Henson business moved out of the building in 2003.
