Trimble Hall is named after Charles Garnet Trimble, a former medical missionary in China and Puget Sound's athletic team physician in the 1930s. Funding for the hall was made possible by a gift provided through the Trimble Foundation from his son, Robert A. Trimble '37. Robert's brother, J. Edward Trimble, was also a '37 graduate, and their sister, Margaret Trimble Campbell, graduated in 1951. Robert U. Trimble, grandson of Robert A. Trimble, graduated from Puget Sound in 1999.
