Einstein began violin lessons at age five, but didn’t enjoy music until age 13, when he discovered Mozart’s violin sonatas. After that, the young genius was hooked and would play the violin in string quartets later as a young adult and throughout the rest of his life.
“Mozart’s music is so pure and beautiful that I see it as a reflection of the inner beauty of the universe itself,” Einstein later told a friend, according to Charles Chaplain: My Autobiography.
