And I just noticed when I was looking up the copyright date of her poem, “Warning” (1961).
She died just over a year ago, January 8, 2018.
Her best known poem starts out,
When I am an old woman I shall wear purple
And a red hat that doesn’t go, and doesn’t suit me,
That second line was the inspiration for the Red Hat Society, a social group for older women.
I once used her poem in my blog. I was contacted by her lawyers, who said she was quite assiduous at protecting it. I thanked them for letting me know and removed it. As the copyright line is now works published in 1923, I’ll be dead before it comes out of copyright.
