David Adjaye, the acclaimed Ghanaian British architect who designed the Smithsonian’s National Museum of African American History and Culture, in Washington, D.C., stepped back from a number of roles Tuesday after The Financial Times reported that three former employees had accused him of sexual harassment and misconduct.1

A spokesman for the British ministry that is overseeing the U.K. Holocaust Memorial and Learning Center, in London, said in an email that the government was “aware of the allegations” and had spoken with Mr. Adjaye’s architecture firm. “They have confirmed that Sir David will not be involved in the U.K. Holocaust Memorial Foundation project until the issues raised have been addressed,” the spokesman said.

The Financial Times reported that one of the women claimed that Mr. Adjaye had sexually assaulted her, including in 2019 in a bathroom at an airport in Johannesburg. It reported that the woman had said that she tried to raise a grievance with Mr. Adjaye’s firm, but that her concerns had been dismissed. Mr. Adjaye told the newspaper that he denied all the allegations, including the alleged bathroom assault.

• 1. Mr. Adjaye resigned as an architectural adviser to the mayor of London, and his work on a British Holocaust memorial was suspended after The Financial Times reported that three women, who were not named, had “accused him and his firm of different forms of exploitation — from alleged sexual assault and sexual harassment by him to a toxic work culture — that have gone unchecked for years.” In a statement on Tuesday, Mr. Adjaye denied the accusations. “I absolutely reject any claims of sexual misconduct, abuse or criminal wrongdoing,” he said in the statement, which was released by Kendal Advisory, a communications and crisis management firm. “These allegations are untrue, distressing for me and my family and run counter to everything I stand for.”
