Duane Clark Larson, 65

Duane Clark Larson, age 65, of Karns, passed away July 8, 2009, at the Methodist Medical Center in Oak Ridge. 

Duane grew up in Lund, Wis., on a dairy farm.  He earned his undergraduate degree from the University of Wisconsin in River Falls and his PhD in nuclear physics from Michigan State University.  In 1968, Duane married fellow physics student Nancy Zander.  Together, they earned their PhDs in 1972 and then joined the staff at Oak Ridge National Laboratory (ORNL).  In 2001, Duane retired from ORNL as Director of the Oak Ridge Electron Linear Accelerator.  The focus of his research then shifted from physics to antique tractors. 

Duane was an avid collector of antique John Deere (and other) tractors, engines, spark plugs, and literature.  He helped found the Karns Volunteer Fire Department, served the Karns Community Club in many different capacities, and was active in the Smoky Mountain Antique Engine and Tractor Association, the East Tennessee Two-Cylinder Club, and the Spark Plug Collectors of America. 

Duane was a member of Grace Lutheran Church in Oak Ridge, Tenn.; funeral services were held there on Monday, July 13. 

Duane was preceded in death by his mother, Kathryn Johnson Larson, and his father, Harvey Larson, of Lund, Wisconsin.  He is survived by his wife, Nancy Larson of Knoxville, Tennessee, and by his daughter Linnea Linton, son-in-law Steve Linton, and grandsons Torin and Asher Linton, all of Asheville, NC.
