Famous Alienist Dies
Dr. Allan McLane Hamilton, famous insanity expert and author of "Recollections of an Alienist" (George H. Doran Company), died on November 24 in his seventy-second year. Dr. Hamilton was the grandson of Alexander Hamilton. Standing at the head of his own profession, he had come into close contact with many prominent men both here and abroad, and had been personally associated, either as expert or witness or adviser, with many of the famous insanity trials of recent years.
In "Recollections of an Alienist" Dr. Hamilton relates his experiences through a long life of interest, not lacking in excitement, in connection with his study of the diseases of the mind. His experiences were not by any means confined to the courtroom and were sometimes attended with great danger, but were always replete with interest.
His memoir, "Recollections of an Alienist" is available for free on google books, here.
