This is one of the most prestigious 18-hole private golf courses in the nation. Its original course design was created by Charles Blair Macdonald, Seth Raynor and Charles Banks on part of the rolling estate owned by William K. Vanderbilt in 1924. In the 50s, when the Long Island Expressway was routed through the northern part of the course, the nearby W.R. Grace estate was purchased and Dick Wilson was retained to redesign the course.

The club was founded by William K. Vanderbilt II in 1924, using part of his Deepdale summer estate at Lake Success. Charles B. Macdonald designed the course, assisted by Seth Raynor. The Deepdale Golf Club was incorporated on 26 October 1924 as a private club with a strictly limited membership. Noted members in the past included the Duke of Windsor and President Dwight D. Eisenhower.

In the 1950s suburbs began to be built in the region, and in 1954 the Long Island Expressway was built, cutting through the north end of the course. The club bought the nearby Joseph Peter Grace, Sr. estate and had a new course designed by Dick Wilson. The Grace mansion was used as the clubhouse.
