The Queen Mother, Elizabeth Angela Marguerite Bowes-Lyon, died 15 years ago today at the age of 101. Queen Elizabeth II's mother died in her sleep on March 30, 2002.

The Queen Mother, who married King George VI on April 23, 1923, reigned as a queen for less than 15 years and was the oldest member of the British royal family at the time of her death. She had outlived many of her siblings and remained in good health until the last few years of her life. At the age of 97, she managed to attend nearly 60 official engagements.

The Queen Mother was Scottish and her parents were the Earl and Countess of Strathmore and Kinghorne. She had nine siblings.

Here are some of her most memorable quotes:

1. “The children will not leave unless I do. I shall not leave unless their father does, and the King will not leave the country in any circumstances whatever," she said when asked if she would leave London during World War II. 

2.  “I'm glad we've been bombed. It makes me feel I can look the East End in the face.” -- After the 1940 bombing of Buckingham Palace.

3. “Your work is the rent you pay for the room you occupy on earth.”

4. “Cowards falter, but danger is often overcome by those who nobly dare.”

5. "Afraid never, never again to be free to think, speak and act as I feel I really ought to."

6. "Nobody is boring. If you find someone or something a bore, the fault lies in you."

7. "I felt it my duty to marry Bertie and fell in love with him afterwards," she said of King George VI.

8. "He loved you all, every one of you, most truly. Now I am left alone to do what I can to honor that pledge without him."

9. "He is my only real friend and one feels one can never have another like him," wrote 19-year-old Elizabeth about King George VI. "I liked him specially because he never tried to flirt or make love or anything like that – which always spoils friendships."

10. "Wouldn’t it be terrible if you’d spent all your life doing everything you were supposed to do, didn’t drink, didn’t smoke, didn’t eat things, took lots of exercise, and suddenly, one day, you were run over by a big red bus and, as the wheels were crunching into you, you’d say, 'Oh my God, I could have got so drunk last night.' That’s the way you should live your life, as if tomorrow you’ll be run over by a big red bus."
