He is known for his work on Liesegang rings. He also helped develop the methods of , a precursor to paper chromatography, published a paper on the possibility of television (years before the discovery of the electron), contributed to chromosome theory, worked on properties of aerosols and gelatins, the origins of silicosis, the role of carbon dioxide in plant life and the mechanism of both black and white and colour photographic processes. The son of a painter (and eventual photographer), Liesegang longed for an artistic career but lacked the ability to draw or paint. His father would later invent a camera and photography would go on to be one of Liesegangs passions. Research into photographic emulsions led to his personal discovery of Liesegang rings. He was not the first person to observe the effect, but they bear his name, as he devoted so much time to researching them. As an heir to the founder of , D\u00FCsseldorf, he also owned a factory producing photographic paper and chemicals. Ed. Liesegang oHG later expanded into optics manufacturing, and sold its photochemical interests. He has published the first German brochure on television : Beitr\u00E4ge zu Problem des elektrischen Fernsehen, 1st edition 1891,"@en . . . . . . .
