I heard a story from a missionary (who has since passed away) about a Gilead student who was suffering from a mental disorder back in Knorr's day. She would become disoriented at night and was known to strip naked and do other strange things. Knorr apparently wanted her back in her home country - and as cheap as possible. He sent her back alone on some sort of cargo ship. She had one of her episodes and jumped overboard, lost at sea.
He supposedly had a reputation of spending as little as possible on missionaries and basically not giving a damn but would spend liberally in updating commodities at h.q.
Update: Turns out this story was mentioned on this forum years ago!
