Known for	Zeleny electroscope electrospray ion mobility

John Zeleny (1872–1951) was a Czech-American physicist at the University of Minnesota, who in 1911 invented the Zeleny electroscope. He also studied the effect of an electric field on a liquid meniscus.^[1]^[2] His work is seen by some as a beginning to emergent technologies like liquid metal ion sources and electrospraying and electrospinning.
