Jadwin Gym, or more formally “the L. Stockwell Jadwin ’28 Gymnasium,” turns 40 this week.

Leander Stockwell Jadwin graduated in 1928 after competing as a hurdler in track and field. He died eight months later in car accident.

Built largely with the money left to the University when Jadwin’s mother died in 1965, the building hosted its first athletic event on Jan. 25, 1969, when Princeton defeated Penn in men’s basketball.

Since then, Jadwin has become one of the key buildings on the Princeton campus and a major venue in the world of intercollegiate athletics. Today it is remains one of the great multi-purpose gymnasiums anywhere, with its five levels and enough floor space for eight football fields.

Jadwin is the home for Princeton men’s and women’s basketball, men’s and women’s indoor track and field, men’s and women’s squash and men’s and women’s fencing, as well as a backup site for men’s and women’s tennis.

It also features most of the Department of Athletics administrative offices, as well as a weight-training center; an indoor turf field large enough to accommodate practices for sports such as baseball, softball, soccer, lacrosse and football and main-court seating for nearly 7,000.

It took four years to build Jadwin, which at the time looked into the open end of Palmer Stadium, which itself had originally been built in four months of 1914 and had been built on that spot because it afforded an unobstructed view of the lake. Jadwin is basically the fifth home for Princeton basketball, which played in Bonner-Marquand Gymnasium (where Campbell Hall now stands) from 1900-02, University Gym from 1903 until fire destroyed the building in 1944, Baker Rink from 1944 until Dillon Gym opened in 1947 and then Dillon from 1947 until 1969.

While it is a facility that might be short on frills, Jadwin is still going strong in its middle age. Any number of events happen under its unique roof each year, and hardly a day goes by without some activity, whether it is Princeton athletics, a summer camp, a practice facility for some team, a high school track meet or the local high school science fair.
