Interestingly, he was the teacher of a certain Albert Einstein at the Polytechnic Institute in Zürich.In 1905, Minkowski heard about the development of the special theory of relativity by his former student, he apparently said: “I would not really have expected that from Einstein.” However, it was Einstein who set the biggest milestone in the research of space-time curvature so far in 1915, with his general theory of relativity.
