Grossmann graduated from the Federal Polytechnic School in 1900. The institution later became known as ETH Zurich.
Grossmann kept careful and complete lecture notes for himself which proved to be a salvation for Einstein. These notes allowed Einstein to catch up on missing material after he missed many lectures due to his own study habits.
Grossmann introduced Einstein to Riemannian geometry around 1912 which was essential for gravity theory. He provided the necessary framework including tensor theory so Einstein could not have completed his work without these specific mathematical concepts.
Einstein and Grossmann co-authored Outline of a Generalized Theory of Relativity and of a Theory of Gravitation. They published this paper together in 1913 and it became one of two fundamental papers establishing Einstein's theory of gravity.
