Smithsonian Institution. But the bill faced significant opposition in Congress due to its cost. Supporters of the African-American museum tried to salvage the proposal by suggesting that the Native Indian museum (then moving through Congress) and African-American museum share the same space. But the compromise did not work and the bill died. Lewis and Leland introduced another bill in 1989. Once more, cost considerations killed the bill. The Smithsonian Institution, however, was moving toward support for a museum. In 1988, an ad hoc group of African-American scholars—most from within the Smithsonian, but some from other museums as well—began debating what an African-American history museum might look like. While the group discussed the issue informally, Smithsonian Secretary Robert McCormick Adams, Jr. publicly suggested in October 1989 that "just a wing" of the National Museum of American History should be devoted to black culture, a pronouncement that generated extensive controversy. The discussions by the ad hoc group prompted the Smithsonian to take a more formal approach to the idea of an African-American heritage museum. In December 1989 the Smithsonian hired nationally respected museum administrator Claudine Brown to conduct a formal study of the museum issue. Brown's group reported six months later that the Smithsonian should form a high-level advisory board to conduct a more thorough study of the issue. The Brown study was blunt in its discussion of the divisions within the African-American community about the advisability of a stand-alone national museum of African-American culture and history, but also forceful in its advocacy of a national museum of national prominence and national visibility with a broad mandate to document the vast sweep of the African-American experience in the United States. The study was also highly critical of the Smithsonian's ability to adequately represent African-American culture and history within an existing institution, and its willingness to appoint African-American staff to high-ranking positions within the museum. The Smithsonian formed a 22-member advisory board, chaired by Mary Schmidt Campbell, in May 1990. The creation of the advisory board was an important step for the Smithsonian. There were many on the Smithsonian's Board of Regents who believed that "African-American culture and history" was indefinable and that not enough artifacts and art of national significance could be found to build a museum. On May 6, 1991, after a year of study, the advisory board issued a report in favor of a national museum, and the Smithsonian Board
