Raphael Seeberger, a merchant, born on 17.08.1890 in Gunzenhausen, was the older son of Rudolph and Jeanette Seeberger, né Oberdorfer. He grew up in the neighbouring house, Hensoltstrasse 23 (at that time Ziegelgasse). In 1920 he married Gella Königshöfer, born on 14.06.1900 in Fürth.

In the year of their marriage, 1920, Raphael Seeberger had taken over the property from his father. It housed the firing kiln and the offices of the Frankonia Ceramics Work.  Living accommodation was in the floor above.  At this time the Seeberger family also owned other houses in the upper part of the Ziegelgasse and in the Seckendorffstrasse, together with a large area behind the houses.  Raphael and his brother Josef ran the business of the glass, china, ceramics and pottery company Frankonia from 1922 until its bankruptcy in July 1931.  All the family's property then passed to the banker Gerst.

In 1931 Raphael registered as a travelling sales representative and his wife Gella ran a grocer's shop in the next door house, number 21, from 1933 to 1936.  The family emigrated to Palestine on 16.07.1936. They lived in Yad Elijahn near Tel Aviv.  Gella Seeberger was in charge of an old age peoples home for German Jews.  She died in 1983.  Justin Gerst and his family moved into the house in 1931.  He was the head of the bank at Rathausstrasse 8.
