Larazus notes that “He was clearly the intellectual leader of the department.”[2] One of his students was E. Frances Seiler who became the first woman to earn a Ph.D in physics at Illinois for her thesis on the color-sensitivity of photoelectric cells.
[4] Kunz made significant contributions to construction of photoelectric cells improving on the methods introduced by Elster and Geitel.
During the fall of 1911, he began a collaboration and friendship with the University of Illinois Observatory director Joel Stebbins that would revolutionize astronomical photometry.
[1] Kunz also collaborated with electrical engineering professor Joseph Tykociński-Tykociner to use a photoelectric cell to photograph sound and reproduce it electronically.
[10] The Kunz daughters Annamarie and Margaret lead a class of a youth session of Louhelen Baháʼí School in the summer of 1937.
