Did Einstein have any close friends outside of work? Albert Einstein, known for his groundbreaking contributions to physics, did have close friendships outside of work. One notable friendship was with Michele Besso, a Swiss engineer and mathematician. Besso and Einstein met while studying at the Polytechnic Institute in Zurich, and their friendship endured for many years. Besso was even described by Einstein as his “best friend” in a letter he wrote to Besso’s family after Michele’s death.

Einstein also had a close friendship with Marcel Grossmann, a classmate from the Polytechnic Institute. Grossmann collaborated with Einstein on the development of the general theory of relativity. Additionally, Einstein maintained relationships with other scientists, philosophers, and intellectuals, engaging in discussions and correspondence on a wide range of topics.

While Einstein was often deeply absorbed in his work, he valued interpersonal connections and intellectual exchange, forming meaningful friendships throughout his life.
