Les Deux Jakes introduced the so-called "Two Jakes" theory that historians would never be able to identify Jake Cutter's true father. This theory--which has become almost an article of faith for most historians in both the Seiber Islands and the Marivellas--will be, I trust, thoroughly discredited by the evidence made public for the first time in this article. Despite recent events, and the clearly erroneous conclusion drawn by Professor Stein that Giacomo "Jake" Lizardo was Jake Cutter's father, I must concede that Professor Stein's monograph did at least attempt to challenge the "Two Jakes" theory.
 Much of the information in this and the next few paragraphs was previously revealed in Lapin's book and/or Professor Stein's monograph. For example, the poor copy of Jake Cutter's birth certificate provided by Blanche Lapin in her book Les Deux Jakes (Boragora: Singe D'Or 1985)(see right), did confirm the name of Jake's mother and his birthdate. Lapin correctly noted that the father's name had appeared to have been altered to read "John Jacob Jingleheimer Schmidt" and relied on this fact to support her conclusion that it would be impossible to determine whether Jake Cutter's father actually was "Jake" Armour or "Jake" Schmidt. Among other things, Lapin was unaware both that Jacob Armour was called "Jake" only by close family and that the real "Harry Potter" was also nicknamed "Jake". She also made no attempt to ascertain "Jake" Schmidt's whereabouts at the time that Jake Cutter was conceived. Professor Oliver Stein subsequently proved in his monograph that Schmidt--then a merchant seaman--could not have been Jake Cutter's father as he was at sea from December 1899 until July of 1900.
Of course, before any of their information was included in this article, it had to be confirmed by my own painstakingly thorough research.
