PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background:

The Wright-Dunbar Interpretive Center (WDIC) Building 16, AKA The Hoover Building, located on the southeast corner of West Third and South Williams Streets on the west side of Dayton, Ohio, the Hoover Block was built by Zachary T. Hoover in 1890 in a Commercial Romanesque style. In its original configuration, the three-story brick building, with a basement had three shops on its first floor, multiple suites on its second floor, and, typical of block buildings constructed at the time, a meeting hall on its third floor. Orville and Wilbur Wright rented the second-floor suite in the northwest corner of the building from 1890 to 1895, out of which they operated their printing business. The WDIC offers additional opportunities to learn about the legacy of the Wright Family, Paul Lawrence Dunbar and their heritage which is unique to Dayton, Ohio.

The WDIC/Hoover Building contains exhibits on the first and second floors. The exhibits begin with an international focus on scientific investigation and invention, the arts, and literature from 1860 to 1940. In the Hoover Block, on the corner of West Third Street and South Williams, was Hale’s grocery store. Exhibits here convey a sense of what it was like to live in this neighborhood in the early 1900s. The original structure was built in 1889 and is a combination of masonry, steel reinforcement and heavy timber construction.
