Lonnie Bunch will leave the Smithsonian at year end after a clash over American history

Lonnie G. Bunch III, the 14th Secretary of the Smithsonian Institution, said on 8 September that he will retire at the end of the year. He has worked at the Smithsonian for nearly 38 years and has held the top job since June 2019. He is the first African American and the first historian to serve as Secretary. He founded the National Museum of African American History and Culture before he took the Castle office.

"It is with very mixed emotions and heartfelt gratitude that I announce my retirement from the Smithsonian," Bunch said in the institution's statement. "I have spent nearly half of my life working at and being part of the Smithsonian family." He told the New York Times the date was not forced by the White House. "It was really just saying, now's the time." He also said the job had been stressful. "At a certain point, I'd like to wake up in the morning and not look at my cellphone."

Chief Justice John G. Roberts Jr., who sits as Chancellor of the Smithsonian, said Bunch had "pursued excellence in the telling of our nation's story" and that the Regents would work with him on a successor. The complex he leaves includes 21 museums, 20 libraries, the National Zoo and a string of research centres. The Secretary answers to the Board of Regents, not to a cabinet secretary. That legal fact is now the political fight.

For more than a year the Trump administration has argued that the Smithsonian presents American history with the wrong emphasis. On 4 July the White House issued a 162-page paper titled "Saving America's Story" that accused museum leadership of "extreme political activism." Later in July the President signed an order requiring warning signs outside the National Museum of American History about what the White House called inaccurate information. An 28 August letter said federal agencies might stop working with the Smithsonian if leadership did not change.

Bunch handed over large volumes of exhibition files when asked and still described the institution as independent. He is 73. He said he is a fighter. The calendar he chose gives the Regents four months to pick a 15th Secretary while he is still in the building. That is an orderly exit on paper. It is also an opening. The next Secretary will take the job after an executive order, a White House history report, and an explicit threat to cut agency cooperation.

The Smithsonian is a 180-year-old hybrid: a public trust created by Congress, funded in large part by appropriations, governed by Regents who include the Chief Justice and members of Congress. Presidents have always had opinions about it. Direct instructions about wall text are newer. Bunch's own career is bound up with the story the administration wants rewritten. He built the African American museum on the Mall. He spent decades as a curator at Air and Space and American History before that.

Readers who have followed the fight already know the adjectives. The concrete change on 8 September is personnel. The man who opened NMAAHC and then ran the whole Institution will be gone by 31 December. The Regents, not the White House, still elect the successor. How freely they do that is the open question Bunch's departure puts on the table.
