From the May 3, 1907 New York Times:

“Milan–Arcangelo Rossi, the tenor, who was with the Conried Opera Company in San Francisco at the time of the earthquake and who, as a result of the fright he experienced, has not since been well, endeavored to commit suicide here to-day.

Recently he lose his voice. This calamity weighed so deeply on his mind that he became insane, and, to-day he cut out his tongue with a pair of scissors. He was taken to a hospital in critical condition.”
