Its interior is an early example of a reinforced concrete slab and \"mushroom\" capital structural system, designed by the engineering firm of Wilbur J. Watson, which was known for its bridges and its pioneering use of reinforced concrete. The property was developed under the Case School of Applied Science's investment policy, meant to strengthen its endowment and encourage industry in the city. The Printz-Biederman Co., a textile and garment maker with a national reputation, moved in during 1934 and renovated the entrance and lobby with art deco details. Later changes included new window sash on the upper floors. The building is now vacant, and plans call for rehabilitation as office and laboratory space.","period_of_significance":"1911 - 1952","architect_builder":"Wilbur J.
