Wendel Mansion, 1934.

In the early 20th century one family could lay claim to the title of most powerful landlords in New York City. The Wendel family owned more than 150 properties in Manhattan and had a net worth of what would be billion dollars today. They owned the land under some of Manhattan's most well known buildings, including the Standard Oil Building and the Time-Life Building. Unlike some flashy real estate moguls (of the past and today) the Wendel's were private in their wealth and their lives. The origins of the families money and land holdings dated to John G. Wendel, a German fur trader who arrived in New York at the end of the 18th century and befriended and then married into the Astor family.

The grandchildren of the first John Wendel included six sisters and a brother who lived in a mansion on the corner of 39th Street and Fifth Avenue. The home had no electricity and no phone, and the inhabitants wore clothes and lived as though they were still in the 19th century. The brother John was known as "The Hermit of Fifth Avenue,” and tightly controlled his sisters' lives until his death in 1914.

The home was constructed around 1856 by the first John Wendel. Sitting on a large corner plot, it had a considerable carriage house and back-yard. The ever-frugal family hung their laundry out to dry in the yard, annoying their neighbors. When the final sister died in 1931 the four-story mansion still had gaslights, an ancient coal stove, and more ancient servants. The large yard, which was then an uncommon open space among the large commercial buildings surrounding it had been used largely as a dog park for the last sister's poodle.

The family's fortune was divided among a number of charities and institutions, including Drew University in New Jersey. The Fifth Avenue mansion was given as a bequest to the school. The home was demolished in 1934. Today a bronze plaque with a image of the home and a bit of family history graces the structure built in its place.
