Art

He was almost blind

Art Tatum [1909-1956] was probably the best jazz pianist ever.
I have little stuff of him but this 'Happy Feet' song gives you an impression of his skills.
The American jazz pianist and physicist Vijay Iver from Berkeley University made a study of the smallest time interval that a human can hear. He called that a Tatum. That are the type of stories (in my newspaper) that make you run.
