Weighing the right way

He also wrote a book called Why Was Lincoln Murdered? (pub. 1937) in which he propounded his theory that the assassination of Abraham Lincoln was set up by Edwin Stanton, the Secretary of War. The book was popular at the time, but attacked by professional historians as consisting of nothing but "disconnected implication and innuendo" (J. G. Hamilton).

In popular culture

Otto Eisenschiml's book inspired the 1942 Broadway play Yours, A. Lincoln.[1] His theory, or one derived from it, was mentioned by the fictional detective Steve Crosetti in an episode of Homicide: Life on the Street. Edward Hyams book, Killing No Murder (Thomas Nelson, 1969), which studied a number of assassinations, accepted this theory, with the added error of supposing Secretaries Seward and Stanton to be next in line after the Vice President. Eisenschiml's book is also referenced in the 2007 Disney film National Treasure: Book of Secrets, when it is mentioned by a precocious child during a scene at the White House Easter egg roll. Similar to the book, the film's premise was partially inspired by pages missing from John Wilkes Booth's diary.
