The John B. Putnam, Jr. Memorial Collection of Sculpture is a group of outdoor sculptures distributed through the Princeton University campus in Princeton, New Jersey. The collection is made up of works from 20th and 21st century sculptors. In March 1968, President Robert Goheen announced that an anonymous donor gave a $1 million fund for the collection in honor of Princeton alumni John B. Putnam, Jr., Lieutenant U.S.A, who was killed in action during World War II. The works were selected based on a committee of alumni who current or former directors of art museums, and the first 20 were purchased in 1969 and 1970.
