This collection (119 items) contains personal letters addressed to Friedrich (later Frederick) Curtze, an immigrant from Corbach, Germany, who settled in Erie, Pennsylvania in 1840, as well as business letters addressed to his son Hermann, an attorney. The first 9 items (1834-1835), written in German, are letters to Friedrich Curtze from German acquaintances and a prospective employer in Boston. Most of the remaining correspondence is made up of incoming business letters that Hermann Curtze received in the 1880s and 1890s. Many items from correspondents in western Pennsylvania and Ohio pertain to particular cases and clients, often regarding estate administration and property ownership. Several business acquaintances sent brief postcards, such as a lawyer from Lancaster, Pennsylvania, who discussed women's property rights (November 2, 1881). Two printed letters relate to the Knights of Honor, a fraternal organization devoted to assisting in the care of the sick, including a key to one of its semi-annual passwords (June 18, 1884). Other items include a letter from Mary Curtze to Hermann Curtze, her brother (1871); personal letters and postcards to Hermann Curtze, often in German; and postcards to other members of the Curtze family.
