Niederstein's Prospect Park Hotel at the intersection of Flatbush Avenue and Malbone Street (Empire Boulevard); ca. 1900.

The proprietor, John Niederstein, Jr., was born in New York in 1871. His father, also John Niederstein, had emigrated from Prussia and owned the Niederstein Hotel and Restaurant in Middle Village, Queens.

The younger Niederstein's hotel — really a tavern with a few furnished rooms for rent attached in order to skirt the Raines Law, which prohibited alcohol sales on Sundays — often made local headlines as an establishment of ill repute.

In response to a letter attributed to "a young man," the Brooklyn Daily Eagle published an investigation into Niederstein's establishment on October 15, 1901, under the headline "Objectionable Resort Located in Flatbush." The report largely corroborated the "young man's" allegations that dancing and drinking in mixed company went on until the early morning hours.

Three days later, the Eagle printed a letter from Niederstein refuting the claims, and asserting that "the dances conducted in his hall are conducted in the straightest possible manner," that his establishment was "the resort of the best element of Germans in this city," and that insinuations of louche behavior and drunkenness were untrue, as were claims that rooms could be rented for racy assignations — but that "if such places are there it is the business of somebody to look after them — not his."

Niederstein's made the news for a variety of reasons, some mundane (social function listings); some odd (Niederstein and his hunting partners "shot a big moose" in the Maine woods); and some salacious, including a 1902 tale of an impromptu wedding featuring a runaway groom with a false name and a wooden leg. (The latter spurred a libel suit against the Eagle, which concluded with a $5,000 judgement in the bride's favor.)

As early as 1900, plans to expand subway service along the BMT's Franklin Avenue and Brighton lines called for razing Niederstein's hotel to make room for a rail yard. Plans eventually shifted to storage tracks beneath Ocean Avenue, with the site eventually becoming part of the Brooklyn Botanic Garden grounds. The Parks Department's 1903 Annual Report indicated that property was "in the process of being condemned," and the hotel itself was likely demolished by 1905.

After the closure of his Brooklyn establishment, Niederstein went on to have a second act in politics: he was elected Queens County clerk in 1906, over the objection of opponents who cited his hotel's reputation. Niederstein died of cirrhosis four years later, shy of his fortieth birthday.
