Obituary of James R. Jenness, Jr.

James R. Jenness, Jr., 97, reposed September 19, 2022 at Mount Nittany Medical Center. He was born February 5, 1925 in Atlanta, GA, the son of James Russell Jenness and Gertrude Denison Jenness. He grew up in Ithaca NY, Dallas TX, Red Wing MN, Clarksville AR, and Fairfield IA. On August 27, 1949 he married Anne Platt, mathematician and talented organist. She died October 31, 2017; they were married more than 68 years. He is survived by sons Russell and Gordon of State College PA, daughter Jane and her husband Gerald Franks of Sterling VA, grandson John Russell Franks of Arlington, VA and granddaughter Anne Marie Franks of Reston, VA.

He might have had a musical career; he played sousaphone and tuba in high school, college and community bands, and trombone in the big-band minor leagues. His college choir director wanted him to major in voice performance. But he was a realist; he majored in physics (BS, Parsons College, Fairfieid IA, 1945) and found prompt employment. He taught high school math at Birmingham IA, then went to SUl (lowa City) and ISU (Ames) for graduate assistantships in physics.

In 1948 he went to the National Advisory Committee for Aeronautics (predecessor of NASA) at Langley Field, VA, where he worked on the development of temperature, pressure and air-speed sensors. In 1951 he went to the U. S. Naval Air Development Center (NADC, Warminster, PA) and worked in infrared optics. At Temple University he taught graduate physics courses at NADC, enabling him to complete a master's degree in 1954. In 1956 he went to State College, PA, where he worked in infrared optics and industrial automation projects for HRB-Singer. After HRB-Singer's 70% downsizing in 1970 he became a full-time Penn State graduate student and completed a PhD in Solid State Science in 1972. From 1972 to 1976 at Scitek, Inc. he worked on the application of physical anomalies for the detection and location of unexploded bombs and shells buried in soil by impact. He went to Penn State's Applied Research Laboratory in 1976 and worked in acoustics, magnetics, and lidar; retired in 1996. He was author and co-author of 25 papers in scientific and engineering journals.

He enjoyed camping, swimming in the Science Park Pool, skiing at Tussey Mountain, playing trombone, baritone or tuba (as the occasion required) in the Little German Band and trombone in the State College Municipal Band. Singing in the choir of Holy Trinity Orthodox Church was the peak of his musical career.
