Karthaus family.

Peter Arnold Karthaus, Sr. (1765-1840) was born in Hamburg, Germany, and emigrated to Baltimore. There he established a mercantile business trading with Germany, Holland, France and the Caribbean. During the War of 1812 he operated at least ten vessels as privateers under letters of marque, although he remained a silent partner in these ventures.

Karthaus was also a pioneer in opening up the trade of the valley of the West Branch of the Susquehanna River and attempting to direct it to Baltimore. Early on he purchased large tracts of land in Clearfield County, Pa., particularly around the junction of Little Moshannon Creek and the West Branch, where the town of Karthaus was eventually built. As early as 1811 he was associated with a fellow German immigrant, the Rev. Frederick W. Geissenhainer, a pioneer in using coal to smelt iron. Agents were sent to open the property and ship coal down the Susquehanna to Baltimore in flatboats.
