The mystery women

http://www.pension-sprachschule.de/anything-german/the-woman-on-the-german-50-pfennig-coin-is-from-oberursel/
I had found out about her in a newspaper article. But today I needed a little more information and I 'googled' it and found this article above.

PS: I still have a hangover and got things mixed up, I was looking for a 'mystery blip' for today, but that is actually Ingeborg's theme for Abstract Thursday. Today's theme is: kindness. This woman showed kindness to the world with her action. I even keep a 'blip calendar' for all the different challenges.
PS: 2 billion have been minted and it is not worth much.
