Momme Andresen (German: [ˈmɔmə ʔanˈdʁeːzn̩], Danish: [ˈmʌmə ænˈtʁeˀsn̩]; 17 October 1857 - 12 January 1951) was a Danish-German industrial research chemist.
[1][2][3] Andresen attended a Volksschule (a local state school) in Niebüll, Schleswig-Holstein, near his birthplace.
His first independent scientific work was to determine the structure of the dyestuff safranin, for the German chemical company Cassella.
His goal was to devise photographic developers which could be stored as stable liquid concentrates which could be diluted for use when needed, rather than having to be made up from several ingredients on the spot.
In 1895, he had a part in devising improvements to the process which led to AGFA commercialising a product in 1898 which both gave better results and was quicker to develop than anything used before.
