Mabel Schuler was born in Wisconsin in 1886. She came to Wahpeton in 1895 to join her father, Gustav, a widower who was getting established in Dakota Territory. Gustav and his brother Eugene operated a farm-implement business and became prominent pioneer architects, attorneys, and construction entrepreneurs. Their homes still stand side-by-side on Sixth Street in what was once Wahpeton’s silk-stocking district, and the Schuler Brothers Building remains a fixture on Main Street downtown.
