Edison’s Ghosts: The Untold Weirdness of History’s Greatest Geniuses by Katie Spalding

“He couldn’t have been like that,” Margaret Thatcher reportedly objected, after seeing the scatologically obsessed character of Mozart in a stage production of Amadeus.

Thatcher simply refused to let those facts impinge on her idea of the artistic hero.
