Three related families are presented on this website: The family of Gustav Maier from Ulm, Germany, who, in the year 1892, had established his family in Switzerland,The family of Albert Meierhofer born at Weiach in the canton of Zurich, and The Anner family, originally from Tegerfelden, canton Aargau. Family archives dating back in part 200 years have been preserved from the Maier and Meierhofer families, and some of these archives have been published recently in form of books, which are presented on this site. Gustav Maier has been a sponsor of the young Albert Einstein at Zurich, from 1895, helping him to get enrolled for studies in physics at the Zurich Polytechnical School (called ETH today). His son Hans Wolfgang Maier has become a professor of psychiatry at Zurich and director of the psychiatric clinic Burghölzli, where he took care of Eduard Einstein, the son of Albert Einstein. Albert Meierhofer, on the other hand, became father of three daughters at Turgi, canton Aargau. The oldest one, Marie (called Maiti), studied medicine at Zurich and made her doctorate in psychiatry with Prof. HW Maier as her supervisor. There, her younger sister, Emmi, met a son of HW Maier, named Gerhard. They fell in love and married in October 1938. They had three daughters: Elisabeth, Beatrice (the author of the books presented on this site) and Verena. Beatrice went to Geneva for studying pharmacy at the University of Geneva and met there Rolf Marc Anner, son of George and Charlotte Anner-Esther. This summary explains why this family history website is called "The Maier Anner Files".

On November 9, 2023, a letter from the German-Jewish writer Gustav Maier was discovered in the Jena City Archives. This letter had lain dormant there since 1897, i.e. for 126 years. Actually, almost all writings by people of Jewish descent in Germany had been destroyed. This particular letter, however, had been assigned to an archive of the Jena Masonic lodge "Friedrich zur ernsten Arbeit", and no one could have guessed that it contained historically important statements on anti-Semitism in Germany. In fact, Gustav Maier states that in Germany, Jewish origins were an odium that attracted hatred and contempt, and that is why he immigrated to the freer Switzerland. There he was also able to informally join the liberal Reformed Zwingli Church with his family. At the time, he could not have known that Gustav Maier had thereby saved part of his family from the Shoah, only anticipated it.

In his travel sketch of Sicily (available in the shop), Gustav Maier describes how he painstakingly translated the guide to the National Museum of Naples into German. Gustav was an enthusiastic visitor to this museum and got into conversation with the museum director because there was no guide in German, despite the large number of German tourists. So Gustav Maier took on this huge task.
