Gary N wrote a biography of Charlie Towns, the founder of Towns Hospital in New York where Bill W was treated, had his "hot flash" (as he called it), and later recruited early members of AA.
Here he covers Charlie as well as William James and Sam Shoemaker.
If you are not familiar or only vaguely familiar with these names, enjoy.
If you are familiar, I suggest you may want to listen because Gary is very good at digging up interesting and insightful pieces from our rich AA history.
