The Center seeks to accomplish this goal by promoting the study of material culture of the era and the social and economic life of Oakland, the East Bay, and the San Francisco Bay Area as represented by the Cohen Bray House. The uniqueness of this house is that it is still lived in by members of the original family. With the help of the friends and the professionals on the board, they have made the effort to preserve and protect the original interiors. Visitors will find the furniture; wallpaper; pictures; rugs; and personal items such as diaries, shopping lists and wedding presents are still in their places.
