How many LGBT items are in the new Smithsonian National Museum of African-American History and Culture and is it enough to please gay historians? It’s a tough question to answer because some ostensibly gay items may not be presented as such. It’s now widely believed, for instance, that “A Raisin in the Sun” playwright Lorraine Hansberry was a closeted lesbian for much of her short life (she died at age 34 in 1965), but to what degree does this factor into her representation in the museum, for instance? Slated to open this weekend with a ceremony Saturday morning in which President Obama will speak, the museum has yet to be assessed by the public. And curators acknowledge it’s impossible to please everyone. Descendants of the Quander family, whose roots can be traced back to slaves at George Washington’s Mount Vernon, have publicly expressed disappointment at not being represented in the inaugural museum displays, for instance. But whether there’s enough LGBT representation overall to please gay historians is yet to be determined.
