Biographical Note

The connection between the Einzig and Field families lies in the marriage of Else Margarete Fraenkel (alternatively Margarete, 1876-1963) and the manufacturer Alfred Einzig (1878-1935) on January 5, 1911. Their daughter Johanna Einzig was born on October 14, 1911. Johanna married Heinrich Biberfeld (1899-1982), a physician from Wandsbek.

Before this marriage, Heinrich had had a son, Hans (alternatively Giovanni or Jack) in 1927 with his first wife Johanna née Hirsch, a physician who died in 1928. Heinrich had then been married to a psychologist, Charlotte née Schweitzer, from 1930 until their divorce in 1933. He and Johanna née Einzig married in 1937 and had a son, Thomas.

In May 1940, Heinrich and Johanna Biberfeld née Einzig immigrated via Italy to the United States, where they took on the names Henry and Joan Field. Henry Field practiced medicine in Brooklyn, New York until 1950, when his license was revoked. Their son Jack Field served in the U.S. Army during World War II. Henry and Joan Field converted to Catholicism in 1952. Joan Field died in 1975, and Henry Field in 1982.
