Northern New Jersey squash dates back to at least the 1920's with memories of Seymour Perkins of a weekend C league. Play increased over the years and in the 1950's several popular tournaments were added to the schedule including the Sea Bright Doubles, Short Hills Club Invitational C and B, Plainfield A, and Montclair B. League play often involved both the New Jersey clubs and as well as clubs based in New York City. The Montclair Squash Club fielded very strong teams then that competed well against their New York counterparts.
In the mid-1970's, the Chatham Club was built as interest and play continued to increase. An A/B league was played for the first time in the 1975-76 season and the NJ State Championships were held for the first time in 1976. As the number of public clubs increased in the mid-1970's, there was a movement to split off from the Metropolitan Squash Racquets Association (New York) which until then had organized the New Jersey leagues.
In 1978, a group of individuals including Bill Block, Jeff Stanley, and Bart Stuck decided to form the NNJSRA and split with the MSRA. The NNJSRA's initial intention was to continue to operate the leagues and tournaments, but to also sponsor instructional clinics for adults and juniors, publish a newsletter and schedules, and further promote the game at all levels. That original mandate continues today. One of the first major efforts of the organization was to establish a major junior tournament for boys and girls in February which is known now of course as the Sy Perkins.
Although the NNJSRA has continued to operate independently of the MSRA it maintains a competitive rivalry with New York City (MSRA) by participating in the bi-annual Hudson River Cup. Since the mid 1990's the NNJSRA has sponsored and organized many hardball and softball squash leagues for all members from elite 'A' to 'D' level, and continues to support the development of both hardball and softball squash for juniors, and for all.
