On May 4, 2012, the Center for Athletics, Recreation and Fitness became the John F. Jaeger Center for Athletics, Recreation, and Fitness. The naming of the Jaeger Center followed the receipt of the largest gift to the general endowment in the College's history, pledged by Trustee John F. Jaeger '65. As an acknowledgement of both Jaeger's recent leadership and his past involvement in the planning and construction of the Jaeger Center, a ceremony and reception were held to celebrate Jaeger's constant advocacy and support of Gettysburg College.
Dedicated on February 5, 2010, the Jaeger Center includes a natatorium with eight competition lanes, five-lane warm-up pool, and 375-seat spectator gallery; a 10,000-square-foot weight and fitness room; multipurpose spaces for aerobics, yoga, Pilates, spinning, and martial arts classes; bouldering area and climbing wall; and expanded facilities for campus recreation and experiential education all while keeping in line with the College's continued dedication to sustainability. It uses at least 27.8 percent less energy and about half the amount of water than a comparable conventional facility, reduces the College's carbon footprint by an estimated 2,445,119 pounds of CO2 emissions every year, and saves more than 3,350,000 gallons of water annually.
