Donald Bertrand Tresidder (April 7, 1894 – January 28, 1948) was the fourth president of Stanford University, serving from 1943 until his sudden death in 1948. He also had a longtime association with Yosemite National Park. Early life Son of John Treloar Tresidder (from Cornwall), Tresidder was born in Tipton, Indiana. Yosemite At the age of 20 he took a trip with his sister to Southern California. The railroad tracks were washed out, so they went to Yosemite Valley instead. There he met many Stanford faculty, who convinced him to enroll in Stanford University. On that visit to Yosemite, Tresidder met his future wife Mary Curry, daughter of David and Jennie Curry, the owners of Camp Curry. Tresidder spent his summers working in Yosemite as a porter and other odd jobs, and was briefly fired for taking his future wife rock climbing up the back side of Half Dome. They married June 17, 1920. After graduating from Stanford he became president of Yosemite Park and Curry Company. During his tenure he presided over the construction of new roads, the Badger Pass Ski Area, and the Ahwahnee Hotel, built in 1927 and now a National Historic Landmark. For many years, Tresidder played the role of the Squire at the Bracebridge Dinner, a lavish Christmas feast which was held every Christmas Day at the Ahwahnee Hotel in Yosemite. His wife played the role of Lady Bracebridge. In 1929 Tresidder asked photographer Ansel Adams to take over as director of the Dinner, which Adams agreed to do. Stanford Tresidder later described himself on arrival at Stanford as an undergraduate: "a gangling youth from the Midwest, wearing a jacket with sleeves too short to cover his long arms, shambling nervously up Palm Drive carrying a battered suitcase. But each student he passed waved and spoke to him cheerfully. At last he encountered President (David Starr) Jordan. The president tipped his broadbrimmed hat, bowed and greeted the young man from Indiana. Tresidder never forgot that welcome." He earned his M.D. from Stanford Medical School in San Francisco; however, he never practiced medicine. While attending medical school he was a member of Phi Chi Medical Fraternity. While serving as president of the Yosemite concession, he was active as a Stanford supporter, raising funds and serving as co-chair of the 50th anniversary celebration. In 1942 he became president of the Stanford board of trustees. When Stanford president
