Benjamin H. and Lydia Mears Tatem came west as newlyweds in 1869 and settled in Helena, where Tatem managed the Unionville mining claims of Philadelphia investors, operated Helena Iron Works, and profited from his interest in the Bald Butte Mine near Marysville. Famous for their hospitality, the Tatems built this stunning Tudor style home circa 1895. In 1901, President McKinley appointed Tatem U.S. assayer of Helena’s federal office at 206 Broadway. Tatem died in 1915. In 1922, at age 82, Lydia Tatem was killed when she fell beneath the wheels of the Kenwood streetcar at Benton and Lawrence. Lieutenant General Samuel Baldwin Marks Young and Anne Dean Huntley Young, sister of renowned Helena physician Dr. Maria Dean, subsequently purchased the home. In 1956, Carroll College acquired the property from Ellen Dean Child Nichols, Mrs. Young’s niece, and the home became Dean Hall, student housing until 1968. Grey granite, characteristic half timbering, and recurrent gothic arches made the house a West Side centerpiece, while exquisite interior woodwork and a magnificent paneled stairway recalled the wealth and taste of Helena’s pioneer elite.
