The house is significant for its illustration of an important phase of Belmont's history, the 19th-century estate development of the town, as well as for its association with the Underwood family, Belmont civic leaders who also made important contributions to the fields of food canning and bacteriology, photography, and landscape architecture.
The house is most closely associated with Lyman Underwood, a talented scientist and naturalist who is remembered for his contributions to the food canning industry, public health, and photography. Lyman Underwood lived in 50 Common Street from his marriage in 1887 to Ida Cushing, until his death in 1929.
