The Old John Hancock Building was constructed by the Boston firm Cram and Ferguson just after World War II. It was constructed in the Art Deco style with tiers and a shallow stepped pyramid on top. Prior to this building, there were no tall buildings in the Back Bay, a Boston neighborhood dominated by row houses and tree-lined avenues. The Hancock Building set precedent for tall commercial building construction in the area, which was later followed by the 749 foot Prudential Tower in 1964 and I.M. Pei's 790 foot John Hancock Tower in 1976.
