Ferdinand von Lindemann (1852–1939) was a notable German mathematician best known for his work in the field of mathematics concerning the foundations of geometry and the theory of numbers. One of his most significant contributions is the proof that pi (π) is a transcendental number, which means that it is not the root of any non-zero polynomial equation with rational coefficients.
