Dr. Gustave "Gus" Charles Erich Mueller passed away peacefully at home on Monday, November 12, 2018 at the age of 86. Born in Princeton, WI on April 3 ^rd 1932, he was the third child of Dr. Gustav and Edith (Schoenberg) Mueller. Formerly the school's band mascot, Gus graduated from Princeton High School in 1949 as Salutatorian and a member of the National Honor Society. After graduation Gus attended the pre-med program at UW-Madison and studied in Edinburgh, Scotland, where he earned his Master's Degree before returning to UW-Madison to complete a second Master's Degree. He then transferred to Harvard Medical School in Boston, MA, graduating cum laude in 1957.

In 1957 Gus married Sara Robbins in a small ceremony in Maplewood, NJ, before moving to Boston to start his surgical internship and residency at Massachusetts General Hospital. Gus joined the United States Air Force in 1962 and was stationed at Wright-Patterson Air Force base in Dayton, OH.  Upon completion of his residency at MGH, Gus attended a thoracic-vascular program in Bristol, England before returning home to Wisconsin. Here he joined the Quisling Clinic where he practiced thoracic and cardiovascular surgery primarily at Madison General Hospital. In 1966 he purchased his family's farm outside Princeton and continued to farm until the late 1980s. In 2000 Sara and Gus built a retirement home on Green Lake and Gus retired from medicine. Gus was active in Green Lake serving on the Green Lake County Board of Supervisors, the Green Lake Sanitary Commission, and the board of Habitat for Humanity for many years.

Throughout his life Gus has enjoyed various building projects, working on the family farm and dedicating himself to his work. Many coworkers and patients have regaled the wonderful stories of his compassionate care and dedication to his patients.
