Alfred Peter Carlslund Jorgensen was a Danish laboratory director. He graduated from Skaarup Seminary 1868, and philosophy candidate in 1873. He studied botany and worked for several years as a teacher in Copenhagen. He studied with Emil Christian Hansen (1842-1909) at the Carlsberg laboratory. At this time botanical-biological analysis gradually became more and more important for fermentation techniques used for beer, and thus Jorgensen joined them. He was one of those who first supported Hansen's pure breeding system and biological methods. / After the new system had been introduced in 1883 at the Gamle Carlsberg brewery and shortly thereafter in other bottom-fermenting breweries, Jorgensen created the first experiments with it at the local top-fermenting breweries in 1885. These also had a lucky outcome. He established a laboratory in 1881, one department of which included teaching, the other mainly the purification and analysis of microorganisms for use and in practice.
