Henry F. Pulitzer
Pulitzer was at one point involved with the Isleworth Mona Lisa, which he acquired from the estate of Hugh O. Blaker by selling his Kensington estate and all its contents. In 1966, he wrote and published a book, Where is the Mona Lisa? in which he presented the case that this painting was the unfinished portrait of Lisa del Giocondo by Leonardo da Vinci.
However, due the fact that Pulitzer was the owner of the painting, his arguments were seen as self-serving and the painting was not even examined by the experts of the time.
