Pierre Wantzel (1814–1848) was a French mathematician best known for his work in geometry and, specifically, for his contributions to the field of classical constructibility problems. He is particularly famous for proving in 1837 that certain problems, such as squaring the circle, trisecting an angle, and doubling the cube, cannot be solved using only a compass and straightedge.
