‎First printing of Gordan's important paper in which he proved that any finite system of binary forms of arbitrary degree had a complete system of invariants. These archievement earned Gordan the name ""King of invariant theory"". (Kolmogorov, Mathematics of the 19th century, p. 85).Paul Gordan, German mathematician, was a major contributor to the field of invariant theory. He collaborated with Rudolf Clebsch on both invariant theory and algebraic geometry, and also developed proofs demonstrating that the numbers e and ? are transcendent numbers, numbers that are not the root of any algebraic equation with rational coefficients. A strict mathematical logician, Gordan commented that David Hilbert's less formal approach to mathematics was ""not mathematics, it is theology."" (Schlager, Science and Its Times, P. 269)‎
