Inside, a rounded hall ceiling adds lovely period elegance. The single-story frame dwelling beautifully illustrates the Greek Revival style in transition. This popular architectural form evolved from the mid-1800s into the twentieth-century gable-front-and-wing, the nation’s most popular form of folk housing. Great Falls pioneer realtor Matthew Dunn purchased the property in 1888, built the home soon after, and was the first occupant. A succession of other early residents included the David Craig family who, along with five boarders, were tenants in 1900. Prominent pioneer attorney James W. Speer and his wife, Grace, owned the property circa 1907 to 1910. Grace taught piano while her husband built his law practice and served as county attorney in 1908 and 1909. He was later elected mayor (1911-1913), state senator (1923 and 1925) and district judge (1948-1956). The Speers’ household in 1910 included their two small children, Grace’s mother, a brother-in-law, and two servants.","sponsor":null,"accessinfo":"Private","lede":"","website":"","related_resources":["<a href=\"https://npgallery.nps.gov/NRHP/GetAsset/8327df66-87d9-43fb-91bf-259b58154a5c\" target=\"_blank\" rel=\"noreferrer noopener\">Read about the Great Falls Northside Residential Historic District</a>"],"factoids":[],"files":{"https://historicmt.org/files/fullsize/3e14493e9c1ba9230dee66d0314be003.jpg":{"id":332,"mime-type":"image/jpeg","title":"305 3rd Ave N.","description":"1. 305 3rd Ave N.<br />\r\n2.
