"In 1879, Bush brought into the firm his son-in-law, T. L. Herbert, who became president on Bush's retirement in 1900. In 1911, following the purchase of the property at 174 Third Avenue, Herbert formed a new company, T. L. Herbert and Sons, to supply other materials related to brick masonry and the two companies shared the building. Over the years the Herbert family businesses expanded to include ready-mix concrete, gravel, and the operation of river dredges and barges in addition to Bush Brick and T. L. Herbert. Though Bush Brick, T. L. Herbert and Sons, and the other family enterprises were consolidated into Herbert Materials, Inc., in 1979, the concern has remained in family hands and is headed by fourth generation descendants of 'Major' Bush.
"Because these businesses—Bush Brick especially—were so successful, they occupy a unique position in the history of Nashville's built enviroment. Bush and Herbert supplied great quantities of the materials which make up many of Nashville's significant buildings. For example, the original Maxwell House Hotel (now destroyed), the Ryman Auditorium, Downtown Presbyterian Church, the original Vanderbilt University campus buildings, and Tulip Street Methodist Church all contain Bush brick. The building itself, with its brick display wall, is architecturally unique in Nashville and is the oldest surviving building associated with this 113-year-old local business."
