One of the earliest case histories in the subject, the remarkable story of Phineas Gage, who accidentally became the first documented case of a prefontal lobotomy.
It has never made sense to me that the action of intentionally removing prefontal lobes became a preferred practice for certain cases, when this case history makes it clear that the action either did nothing or made him significantly worse. YEt up until the early 1970's in the United States over 40,000 people were treated with vartiations of this technique. One of note was Rosemarie Kennedy (JFK's sister) who received the operation when her father complained of her "moodiness". (See this page.)
Just an aside concerning where we've been in the not too distant past.
