Nelson said he’s known Windmuller-Luna since she was a graduate student at Princeton. “She is richly deserving of the Brooklyn position,” he said. “It’s also noteworthy that Brooklyn, even with these hires, has one of the most diverse curatorial staffs of any major American museum.

Nelson also pointed to the lack of controversy surrounding Sawyer, the incoming photography curator, and said the whole controversy is enigmatic of a larger problem in the art world.

“The frustration is based on larger systems of exclusion in the art world,” he said. “It’s a larger problem in art history and curatorial fields that we’ve done a very poor job of attracting people of color not only to African art but art history in general.”

“Why aren’t you all equally upset that Brooklyn hired a white curator for photography?” Nelson tweeted. “It’s because of your misconceptions that those who study African art are black and those who study other things aren’t. You all need to check your assumptions.”
