Hosmer Curtis, a brother of Henry B. Curtis, may have built the house around 1840. Hosmer Curtis is sometimes referred to as the “Father of the Knox County Bar.” He came to Mount Vernon from Connecticut in 1815, serving as county prosecutor, state legislature, and attorney. He was also known to teach legal studies to young students in Knox County. In 1850, when the Historical Society of Knox County was formed, Hosmer served as first its president. Hosmer Curtis remained in Mount Vernon for about forty years, until he moved to Iowa in 1858 and remained there for the rest of his life.
502 North Main Street is a simple house with a three-bay wide front façade. It features trabeated transom and sidelights around the front entrance. The windows of the house may have been replaced at a later time. False shutters, a bay window, and a Colonial Revival porch are later additions to the house.
