On 9 October 2026, three stumbling stones were laid for communists that were part of the resistance: Johann Riemer, Karl Xaver Riemer and Leo Eichmüller. The men were friends during their incarceration in Dachau Concentration Camp. Initiator of the laying was Ines Eichmüller, the great-niece of Leo Eichmüller. All three survived Dachau.

Johann Riemer was born on 11 June 1910 in Nuremberg. His parents were Johann Michael and Marie Riemer, née Gaisberger.

He grew up in Nuremberg and, with the exception of travels as a journeyman and time spent in Chemnitz in 1928, he lived with his parents at Sperberstrasse 46. He was a painter.

On 1 July 1933, he married Johanna Böhm. She was born on 4 July 1914 in Nuremberg. The couple moved into the house at Fetzergasse 20 on 5 July 1933. The house was destroyed in the war. Today, the structure Neue Gasse 32 is located on the property. On 1 August 1933, their daughter Anita was born. The family only lived together for about a month, as on 27 August 1933, Johann was arrested and taken into so-called “protective custody”.

Like his brother Karl, Johann was a member of the Communist Party of Germany and therefore active in the resistance. Karl was already taken into “protective custody” in April 1933 and sent to the Dachau Concentration Camp; Johann was forced to follow him in August. Both survived there for 12 years. In Dachau, the brother were friends with the Nuremberg prisoner Leo Eichmüller.

While Johann was a prisoner in Dachau, his marriage ended in divorce. After his release, he married a second time. His wife was Karoline Hildegard, née Schaurer. She was born on 9. April 1918 in Nuremberg.
