Hudson Maxim was an inventor/scientist
He was a confidant of Presidents, having spent time with at least three. While he maintained a town house in Brooklyn, NY, Maxim spent most of the year in Hopatcong when not traveling. In 1906, Maxim built his famous Venetian style boat house, which would dominate the west shore for the next 50 years. Built of stone and wood with two steel girders, it projected out over the water and resembled a medieval fortress. It had three floors and stone fireplaces. Maxim died May 6, 1927 at his house in Hopatcong. In 1929, a monument in his honor was erected at Hopatcong State Park. While his main house and boat house were regrettably torn down in the late 1950’s, several other Maxim Park buildings survive today. The two guest houses and garage are private residences, and the unique round ice house/observatory has been converted to a rathskeller.
