Rudolf Krügener (* 8 December 1847 in Elberfeld; † 22. September 1913 in Dresden) was a chemist who led a branch of Agfa in Frankfurt am Main. Since he was handicapped, wearing a self-made leg prosthesis, he developed for himself (with the help of a master mechanic named Krücke) Dr. Krügenersche Taschenbuch Kamera (Dr. Krügeners's pocketbook camera), one of the smallest cameras of its time, with dimensions of 45×100×140mm. A novelty was the magazine for 24 plate exposures. It was an economic success.

Krügener founded Dr. Rudolf Krügener, Photochemisches Laboratorium und Fabrik photographischer Apparate Frankfurt-Bockenheim, a company that produced lenses, photo chemicals and cameras. He expanded the company with a plant in Furtwangen. His company produced 100 camera models and kept up with technology. Dr. Krügener favoured the plate format 9×12cm .

Around the time of the merger of the company with others to ICA, his sons became managers there: Walter Krügener as boss in Furtwangen, Dr. Hermann Krügener a director of ICA.
