Bettina Bien Greaves, Ludwig von Mises’ student and bibliographer, has passed away at the ripe old age of 100.  She was a brilliant and extraordinarily-productive woman, a great friend of the Mises Institute in particular and the freedom movement in general.  She was still attending Mises Institute academic conferences just a few years ago in Auburn.  There seems to be somewhat of a fountain-of-youth aspect to Austrian economics!
