||1959: Jakob Nielsen dies ... mathematician known for his work on automorphisms of surfaces. Nielsen transformations are certain automorphisms of a free group which are a non-commutative analogue of row reduction and one of the main tools used in studying free groups, introduced by Nielsen to prove that every subgroup of a free group is free (the Nielsen–Schreier theorem), now used in a variety of mathematics, including computational group theory, k-theory, and knot theory.
