The biography of Harry Johnson and his family has to be largely rewritten, as numerous previously unknown official documents paint a new picture. Read more about this at https://mixology.eu/harry-johnson-the-heidelberg-years/
Summarised briefly, these documents prove that Harry’s first marriage was to Bertha Paul. It was not she who went to Heidelberg with their children, but his second wife Franziska Püttner. She divorced him in 1913 and married the most important German theatre director of the time, Dr Alwin Kronacher. Franziska died in Hamburg in 1945.
Harry and Franziska’s daughter Sigrid did not live in the USA, but married the former Olympic athlete and Doctor of Philosophy Albert Wilhelm Jesinghaus in Leipzig in 1926. Both died in Hamburg in 1968.
Harry and Franziska’s son Herbert died in Manhattan in 1939. His body was transferred to Germany.
The official documents suggest that Harry was at times married to his three wives at the same time: Bertha in Manhattan; Franziska in Hoboken and later Heidelberg; Martha in Berlin.
For my English-speaking readers, please note: More questions have arisen and I amcontinuing to research. Once the research is complete, you’ll read everything in English translation on my blog. If you are very curious, I kindly ask you to translate the post on Mixology with https://www.deepl.com/translator, because all the important documents are quoted in it.
