On December 24, 1928 Albert Einstein wrote a birthday letter on Emanuel Lasker’s 60th birthday, in which he said: “Emanuel Lasker is one of the strongest minds I ever met in my life. A Renaissance man, gifted with an untamable urge for liberty; averse to any social bonds [...]. As a genuine individualist and self-willed soul, he loves deduction; and inductive research leaves him cold [...]. I love his writings, irrespective of their content of truth, as the fruits of a great original and free mind”.
