Theodor Otto Hahn was born in Dresden in 1870, and came to Munich in 1898, as a Kunstmaler (artist decorator). His first known address was in 1900 & 1901, at Theresienstraße 128, 2nd floor. In 1902 he had moved to Zieblandstraße 18a, 1st floor. By 1903, he was at Neureutherstraße 25, 4th floor, until 1911 when he moved to Schleissheimerstraße 83, 2nd floor. By 1915 he had formalised his business, by creating a company, named Kakam Porzellan. In 1918, this name was changed to
Kakam-Kleinkunst. In 1926, it is believed that he took on partners in the business, as the name changed again, this time to Kakam-Kleinkunst Hahn & Co. Also several artist's initials (as yet unidentified), but including Th. Otto Hahn, have been reported to having been seen using the Kakam trade name. By 1927 the street name had changed to Schleissheimer Straße. This partnership was still trading during 1930, but by 1935, Hahn's business name had reverted to Theodor Otto Hahn, Kunstmaler, based at Heßstraße 49, 3rd floor. He was still listed there in 1941, but by 1953, his listing had disappeared.
There was another Theodor Otto Hahn (possibly his father?) who had a workshop in Klotzsche, now a northern suburb of Dresden and who painted in the Dresden style. His workshop, known to have closed by 1906, used a rooster with Klotzsche underneath as its trade mark.
