Los Angeles (CNN) -- Juanita Moore, the third African-American actress to ever get a supporting actress Oscar nomination, died of natural causes at her Los Angeles home Tuesday, her grandson said. She was 99.

Moore worked right to the end, preparing for a stage reading of a new play and helping her actor grandson learn lines, Kirk Kellykhan said,

"I just got cursed out that morning about learning my lines," Kellykhan said. Moore was helping him prepare for the lead in the West Coast production of the Broadway play "The Wedding Man," he said.

She was scheduled to take part in a January 17 reading of a play based on Michael St. John's book "Hollywood Through the Backdoor," her grandson said.

Moore was nominated for a best supporting actress Oscar in 1960 for Douglas Sirk's "Imitation of Life." She played a housekeeper whose daughter passes for white.

A Los Angeles native, she began her entertainment career as a Cotton Club chorus girl and a film extra. At the same time, she worked on her acting skills on stage in the Ebony Showcase Theater.

Moore's feature film debut came in 1949 when she played a nurse in "Pinky."

Most of her roles in the 1950s were as domestics, until she was cast as Annie Johnson in "Imitation of Life." The story was about Johnson's light-skinned daughter denying her racial roots.

The lack of roles for African-American actresses in the early 1960s made it difficult for Moore to find big-screen jobs despite the accolades for her work. She acted in supporting roles in 1961 in "Tammy, Tell Me True" and in 1963 in "Papa's Delicate Condition." Moore did land a significant role as a nun in the 1966 hit "The Singing Nun."

CHAPTER VII

IN WHICH MIKE IS DISCUSSED

Trevor and Clowes, of Donaldson's, were sitting in their study a week after the gramophone incident, preparatory to going on the river. At least Trevor was in the study, getting tea ready. Clowes was on the window-sill, one leg in the room, the other outside, hanging over space. He loved to sit in this attitude, watching some one else work, and giving his views on life to whoever would listen to them. Clowes was tall, and looked sad, which he was not. Trevor was shorter, and very much in earnest over all that he did. On the present occasion he was measuring out tea with a concentration worthy of a general planning a campaign.

"One for the pot," said Clowes.

"All right," breathed Trevor. "Come and help, you slacker."

"Too busy."

"You aren't doing a stroke."

"My lad, I'm thinking of Life. That's a thing you couldn't do. I often say to people, 'Good chap, Trevor, but can't think of Life. Give him a tea-pot and half a pound of butter to mess about with,' I say, 'and he's all right. But when it comes to deep thought, where is he? Among the also-rans.' That's what I say."

"Silly ass," said Trevor, slicing bread. "What particular rot were you thinking about just then? What fun it was sitting back and watching other fellows work, I should think."

"My mind at the moment," said Clowes, "was tensely occupied with the problem of brothers at school. Have you got any brothers, Trevor?" What are the answers to this following set of questions: 1. Had there been an incident with a gramophone?
2. Who does Trevor think is a silly ass?
3. Was his mind occupied with thoughts of girls?
4. Then who?

7. What type of chap does he think Trevor to be?
8. How much butter does Trevor need to have a good time?
9. What else does he need?
