In August of 2022, the University of Michigan Library announced that one of its most prized possessions, a manuscript said to have been written by Galileo around 1610, was in fact a 20th-century fake. This brought renewed attention to the checkered career of the man named as the likely culprit: Tobia Nicotra, a notorious forger from Milan.

Nicotra hoodwinked the U.S. Library of Congress into buying a fake Mozart manuscript in 1928. He wrote an early biography of the conductor Arturo Toscanini that became better known for its fictions than its facts. He traveled under the name of another famous conductor who had recently died. And in 1934 he was convicted of forgery in Milan after the police were tipped off by Toscanini’s son Walter, who had bought a fake Mozart from him.

Here's his explanation of what had motivated his many forgeries, which were said to number in the hundreds: “I did it to support my seven loves.” When the police raided Nicotra’s apartment in Milan, they found a virtual forgery factory, strewn with counterfeit documents that appeared to bear the signatures of Columbus, Mozart, Leonardo da Vinci, George Washington, the Marquis de Lafayette, Martin Luther, Warren G. Harding, and other famous figures.

Investigators had also found a sort of shrine to his seven mistresses, at least according to The American Weekly. The article described a room with black velvet-covered walls, with seven panels featuring paintings, sketches, and photographs of the women with fresh flowers in front of each. “Incidentally,” the publication added, “he had a wife.”
