Larry Michael Rosenbaum passed away on September 7, 2026 at the age of 74 at Parkwest Medical Center in Knoxville, Tennessee, following several years of declining health due to Parkinson’s Disease. A Celebration of Life will be held Saturday, Nov. 14 at 2 p.m. at ORUUC.

Larry was born October 15, 1951 in Wilkes-Barre, Pennsylvania to Bessie and Isadore Rosenbaum. He earned his Bachelor’s Degree from Cornell University and his Master’s Degree from the Massachusetts Institute of Technology (MIT). He worked in Oak Ridge at K-25 and Oak Ridge National Laboratory, retiring after 40 years.

Larry discovered West Coast Swing dancing in 2011 and went on to dance competitively with his dance partner, Kelli Rainey. Larry was shy most of his life, but dancing brought out a joyful, social side of him. Larry was Jewish and became a member of Oak Ridge Unitarian Universalist Church. He particularly enjoyed participating in ORUUC’s music program in the choir, Mighty House Band, Sorta Singers, and Bifocals. Despite multiple hospitalizations, Larry continued playing music until just weeks before his passing.

He is survived by his wife of almost 50 years, Susan Kytle Rosenbaum; their son, Philip; daughter Kelly Walker and son-in-law Nicholas; sister Ilean Molish and brother-in-law Richard; as well as three nephews and a niece. Larry was preceded in death by his parents, Bessie and Isadore, and a young daughter he shared with Susan, Erin Rebekah Rosenbaum.

The Rosenbaum family thanks all their loved ones, and nurses Courtney and Lisa, for support during Larry’s final years. In lieu of flowers, the family requests donations be made to ZZ Dance: Kindness in Motion dance studio, which provides dance classes for children with special needs. Please send to 2091 Springdale Rd Unit #5, Cherry Hill, NJ 08003.
