Max Dehn Max Wilhelm Dehn (November 13, 1878 – June 27, 1952) was a German mathematician most famous for his work in geometry, topology and geometric group theory. Born to a Jewish family in Germany, Dehn's early life and career took place in Germany. ...

's theory of the equivalence of polyhedra under polyhedral dissection and reassembly ( scissors-congruence), extending and generalizing the theory with an entire class of new relations. Nicoletti collaborated in the writing of ''Enciclopedia Hoepli delle Matematiche elementari e complementi'' (published from 1930 to 1951) with the contribution of two monographic articles: ''Forme razionali di una o più variabili'' (Rational forms of one or more variables) and ''Proprietà generali delle funzioni algebriche'' (General properties of algebraic functions). A leading expert in mathematics education, he edited with Roberto Marcolongo a series of successful editions for secondary schools. Nicoletti was an Invited Speaker of the ICM in Rome.
