In 1966 he received his Ph. D. in Physics from Vanderbilt and began research at the School for Aerospace Medicine. He studied medical Physics at M. D. Anderson. Upon leaving the Air Force he joined Holt- Krock Clinic in Fort Smith, Arkansas.
Lloyd sang in choral groups and his church choirs. He volunteered at the church in other ways. He was active in professional organizations for Medical Physics. He was active with the symphony board and community theater. It gave him great pleasure to teach math classes in the evening first at San Antonio College and then Westark Community College/ University of Arkansas Fort Smith.
In one of his last evaluations, a student wrote, “He is just a sweet old man trying to help us understand algebra.”
The family would like to thank Dr. Shanmugam, Martin Health Centers, and Synergy Caregivers for their wonderful care. Also, Mary Krutke, a caregiver who became a dear friend.
