Presiding over the pristine core of Park Slope at the intersection of Eighth Avenue and Union Street, this magnificent Renaissance Revival former mansion exudes a rich and storied past. One of its first owners was the pioneering physician and surgeon H. Beeckman Delacourt (d. 1930), a member of the Montauk Club who mingled with the motley crew of figures - both famous and infamous - that graced turn?-?of?-?the?-?century? New York?. In the early 1900s, the good doctor's neighbors along this northern stretch of Eight?h? Avenue, also known as Sportsmen's Row, included titans of horse racing, empresarios of Vaudeville and Coney Island, and prominent manufacturing families, not to mention Tammany Hall mayor William Gaynor as well as the powerful Pinkerton family of private detectives. Today this rare, 20'-wide, five-story architectural gem is configured as offices on ?the ?ground level, and four sprawling floor-through apartments above, offering infinite possibilities to both the discerning nest seeker and investor alike. Showing by appointment.
