Ebert quotes from Le Gon's obituary in the London Independent about Le Gon's brush with Ronald Reagan in 1950. She'd have known what kind of president was coming, and was probably unsurprised when Reagan ignored AIDS in its early years.
"She played maids to Maria Montez in Arabian Nights (1942), Ann Miller in Easter Parade (1948) and Betty Hutton in Somebody Loves Me (1952). Tiring of maid roles, Le Gon faced humiliation in 1950 when she joined a group of black actors to call on Ronald Reagan, then president of the Screen Actors Guild. They raised their concerns about the stereotyping of black actors, but Reagan showed no interest: "We tried to get him to intervene for us, but he wasn't the least bit sympathetic. He didn't even lie about it."
