Jean Dufresne (14-02-1829 - 13-04-1893) chess player, composer and author

Jean Dufresne [Wikipedia]

He is known for the Evergreen game with Adolf Anderssen, whose student he was and for his "Kleines Lehrbuch des Schachspiels" (1881). What's he doing here?, you may righteously ask. Dufresne also composed some studies, of which you can find a sample below. Our readers will enjoy his anthology published in the end of the 19th century and kindly hosted by Anders Thulin:
"Sammlung leichterer Schachaufgaben, I" (1881)
"Sammlung leichterer Schachaufgaben, II" (1882)
"Sammlung leichterer Schachaufgaben, III" (1887)

An easy study:

1.Qxa7#, isn't it? But then what was Black's last move in the diagram position?
There is no legal last move for Black, which means that White played the last move and Black to play: 1...Qb8#!
