Albert Einstein
A German theoretical physicist, who played the piano and violin.
Music was no mere diversion. On the contrary, it helped him think. ‘Whenever he felt that he had come to the end of the road or faced a difficult challenge in his work,’ said his son Hans Albert, ‘he would take refuge in music and that would solve all his difficulties.’ […] …a friend recalled, ‘Then suddenly, in the middle of playing, he would announce excitedly: I‘ve got it! As if by inspiration, the answer to the problem would have come to him in the midst of music.’
