Berta (sometimes also spelled Bertha and Bertel) Braunschweiger, née Heinemann, only lived in Bad Kissingen for a short time, during which time she worked as a kindergarten teacher at the Israelite Children's Sanatorium. She was born in Bayreuth in September 1893, the eldest daughter of David Heinemann and Rosa, née Goetz, and had two younger siblings, Max (1896-1956) and Irma (1905 - 1970).

The family moved to Würzburg in the following years, where the younger siblings were born. Berta's father was a merchant and tailor by trade and ran the textile company "Heinemann und Sohn" there with his son Max.

As a young woman, Berta moved to Salinenstrasse in Bad Kissingen for the first time in May 1912 and was employed there during the summer season as a kindergarten teacher in the Israelite children's sanatorium. She worked there again the following year before returning to Würzburg in August 1913.

In July 1919, she married Bernhard Braunschweiger, a cattle dealer born in Wüstensachsen, and moved to the Hessian community in the district of Gersfeld (now the district of Fulda), where there had been a relatively large Jewish rural community for centuries. Their four children Lothar (Lou) (1920-2011), Beatrice (1921-2001), Edith (1924-1940) and Reinhard (later Steven) (1927 - 2014) were also born there. According to a list of "Jewish addresses and businesses before 1938" on Alemannia Judaica Wüstensachsen, Bertel Braunschweiger ran a hat and clothes store at Rhönstraße 4.

Fortunately, the entire family managed to escape the Nazi tyranny; the daughters Edith and Beatrice were brought to safety in New York in December 1934, presumably on a Kindertransport (Jack and Herbert Steinberger were also on board), Bertha emigrated in March 1936 and the rest of the family followed in March 1937. Berta's parents David and Rosa and her three siblings also managed to escape to the United States.

After emigrating, the Braunschweiger family lived in New York and temporarily in Florida; some of the family members can also be found in the databases under the name "Brown".

Berta Braunschweiger died in New York in January 1983 at the age of almost 90.
