Wolfke is known for his discovery of two types of liquid [[helium]], of which He II is still the only known superfluid liquid. He did ground-breaking work in [[holography]], an area of optics dealing with the creation and recording of three-dimensional images: in 1920 he divided the process of creating such images into two distinct phases by using two beams of light, each having a different wavelength. [[Dennis Gabor]], the 1971 Nobel laureate in physics, named Mieczysław Wolfke as one of his precursors in the development of holography. {{BD|1883|1947|Wolfke, Mieczyslaw}} [[Category:Polish physicists]] [[Category:University of Wrocław alumni]] {{physicist-stub}} [[pl:Mieczysław Wolfke]]
