The community of St. Peter was initially, and for a very brief time, known as Rock Bend, a name taken because of the presence of a sharp bend in the course of the Minnesota River on the east side of the settlement. The name was used probably from late in 1853 until sometime in 1854. The envelope shown here, addressed to Charles E. Flandrau (1828-1903), who was living in the area at the time, is one of only a few objects that survived with the name "Rock Bend" on it. Flandrau, himself, became a very prominent resident of the State of Minnesota. Among many other duties during his lifetime, he commanded the defenders of New Ulm in August of 1862 and later served on the Minnesota Supreme Court.
