“LOUISE BOURGEOIS made art almost up to the day she died on May 31st 2010. She was in her 99th year. Bourgeois had her first major retrospective at the Museum of Modern Art in New York in 1982. She was 71 at the time. Some might have taken this as a sign that it was time to retire. But Bourgeois went on to produce her most ambitious works—large-scale spider sculptures and dreamlike installations that she called “cells”—when she was in her mid-80s. She had trouble with mobility in her old age, but she enjoyed a clear head. Her steely will was legendary.”
