Hattie McDaniel (June 10, 1895 - October 26, 1952) was an American stage actress, professional singer-songwriter, and comedian. She is best known for her role as "Mammy" in Gone with the Wind (1939), for which she won the Academy Award for Best Supporting Actress, the first Academy Award won by an African American entertainer. In addition to acting in many films, McDaniel was a radio performer and television star; she was the first black woman to sing on radio in the United States. She appeared in over 300 films, although she received screen credits for only 80 or so.

In August, 1950, McDaniel suffered a heart ailment and entered Temple Hospital in semi-critical condition. She was released in October to recuperate at home, and she was cited by United Press on Jan. 3, 1951, as showing "slight improvement in her recovery from a mild stroke."  McDaniel died of breast cancer at age 57 on October 26, 1952, in the hospital on the grounds of the Motion Picture House in Woodland Hills, California. She was survived by her brother Sam McDaniel. Thousands of mourners turned out to celebrate her life and achievements. In her will, McDaniel wrote, "I desire a white casket and a white shroud; white gardenias in my hair and in my hands, together with a white gardenia blanket and a pillow of red roses. I also wish to be buried in the Hollywood Cemetery"; Hollywood Cemetery, on Santa Monica Boulevard in Hollywood, is the resting place of movie stars such as Douglas Fairbanks and Rudolph Valentino. Its owner at the time, Jules Roth, refused to allow her to be buried there, because, at the time of McDaniel's death, the cemetery practiced racial segregation and would not accept the remains of black people for burial. Her second choice was Rosedale Cemetery (now known as Angelus-Rosedale Cemetery), where she lies today.  In 1999, Tyler Cassidy, the new owner of the Hollywood Cemetery (renamed the Hollywood Forever Cemetery), offered to have McDaniel re-interred there. Her family did not wish to disturb her remains and declined the offer. Instead, Hollywood Forever Cemetery built a large cenotaph on the lawn overlooking its lake. It is one of Hollywood's most popular tourist attractions.  McDaniel's last will and testament of December 1951 bequeathed her Oscar to Howard University, where she had been honored by the students with a luncheon after she had won her Oscar. At the time of her death, McDaniel would have had few options. Very few white institutions in that day preserved black history. Historically, black colleges had been where such artifacts were placed. Despite evidence McDaniel had earned an excellent income as an actress, her final estate was less than $10,000. The IRS claimed the estate owed more than $11,000 in taxes. In the end, the probate court ordered all of her property, including her Oscar, sold to pay off creditors. Years later, the Oscar turned up where McDaniel wanted it to be: Howard University, where, according to reports, it was displayed in a glass case in the university's drama department.
