Physics department
Kunz arrived at the University of Illinois in 1909 as a theoretical physicist. He taught most of the graduate courses and supervised half of the Ph. Ds up to 1929. Larazus notes that âHe was clearly the intellectual leader of the department.âBOOK, The Loomis Legacy, David Lazarus, 1987, University of Illinois at Urbana Champaign, 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.WEB,weblink History of excellence, University of Illinois, 3 February 2011, Kunz also wrote papers on and gave public lectures on relativity.* NEWS- NEWS

Photoelectric cells and astronomical photometry
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. Kunz's photoelectric cells were many times more sensitive that what was available commercially and therefore able to detect faint star light. Kunz's cells would be used at half a dozen observatories all across the nation including Yerkes Observatory, Lick Observatory, and Washburn Observatory. Kunz also accompanied Stebbins and four solar eclipse expeditions beginning with the Solar eclipse of June 8, 1918 to measure the total light of the solar corona with the photoelectric photometer. The collaboration between Stebbins and Kunz continued until Kunz's death in 1938.Kunz also collaborated with electrical engineering professor Joseph TykociÅski-Tykociner to use a photoelectric cell to photograph sound and reproduce it electronically. When Tykociner demonstrates the first sound-on-film motion picture recordings in 1921 in Urbana, the projector had a Kunz cell at its heart.Family
Jakob Kunz was the son of Jakob and Anna Marie Weber Kunz. He was married to Anna Bolliger about 1913MAGAZINE, Margaret Kunz Ruhe
