Schweitzer-Guggenheimer Letter Collection
This collection of letters centers on Isaac Schweitzer, a merchant from the community of Mühringen who immigrated to the United States in the 1860s. He remained in the United States for almost twenty years, eventually marrying Isabella Guggenheimer, the U.S.-born daughter of two German immigrants. Eventually, Isaac returned to Germany with Isabella and remained there for the rest of his life.
