Kurt Reidemeister

Kurt Reidemeister was a German mathematician known for his contributions to knot theory and topology. He lived from 1882 to 1971. Reidemeister is particularly famous for introducing the Reidemeister moves, which are a set of three simple manipulations that can be performed on knot diagrams. These moves are fundamental in the study of equivalence of knots and links, as they provide a way to determine whether two knot diagrams represent the same knot.
