Inscription.
Located on the northwest intersection of St. Clair and Fourth streets, the Beaver Power Building is one of the few large structures that survived the flood and fire of 1913. The building was constructed in 1910 by Dayton industrialist and Beaver Soap Company owner Frederick Beaver. An early example of reinforced concrete construction in Dayton, the building provided factory and shop space mainly to small enterprises. However, the fourth floor of the building was rented by the Dayton Engineering Laboratories Company (Delco) as its first home in 1911. Delco manufactured its first electric starters for the 1912 Cadillac in this building, ensuring its reputation for pioneering innovations for the automobile industry.
