20th Century Greatest Classical Pianist: Glenn Gould (Canadian)

When he was 10 years old, he injured his back falling from a boat ramp and his father made him an adjustable-height chair, so Gould could sit very low at the keyboard.
Here he is at the age of 14
The chair allowed him to pull down on the keys instead of striking them from above; he used it for the rest of his life and took it with him everywhere. To Gould it was "a member of the family".
Glenn Gould entered the Music Conservatory at the age of 10 and graduated at 12 with the category of a proffesional. He he was able to memorize full pieces before playing them and once dared a friend to name a composition he couldn´t play instantly and by heart.
