Les married Dr. LaNelle E. Reese in 1962. LaNelle, who led the School of Nursing at Purdue University for many years, helped Les bridge the gap between engineering and medicine. Les’s research on electrodes and cardiovascular, neural, and respiratory devices and restorative tissues resulted in numerous diagnostic and therapeutic methods affecting thousands of lives. He had many patents; one of them brought the largest out-licensing deal in the history of Purdue University.

He was always available to those who requested time with him, no matter who or why. He was frequently the first person arriving at a meeting place, and many times he arranged the desks and brought additional chairs to the room to make the meeting more pleasant and efficient.
