good--yes
kind--yes
If your MD friend's intention is good, then he will surely be known by his works, just as Uncle Bill is known by his.

I would suspect that the recipient of the funds would in some form or manner express his gratitude and let his benefactor know about his successes as he matriculated. Things such as forwarding an authentic copy of his grade report,possibly through Sgt Karda to Uncle Bill, each quarter,which could then be forwarded on to the Doctor.
If I had such a benefactor, I would gladly provide such information along with some pictures of the school,etc.
