The building at 627 Main Street in Waltham was built by George Miller in 1856 and was designed by his son-in-law, architect Henry Hartwell. The building was briefly the Waltham Hotel, but after the civil war the upper floors were remodeled for offices and club rooms with commercial shops continuing on the first floor. Called Miller’s Block, it originally had a central arched passageway leading to livery stables in the rear (the ground floor facade was much altered in the 1940s). In 1867, Miller sold the building to Samuel B. Whitney, who renamed it the Central Block. Alvin Jewell, a pioneering weathervane manufacturer, was killed while erecting a new sign on the building when the scaffolding collapsed. The selectmen of Waltham met in he building until 1875 and Waltham’s first telephone exchange was located on the first floor.
