"WebbOstrogradsky also wrote several papers on the theory of algebraic functions and their integrals ( ibid, pp. 13–44, 175–179). The foundation of this theory was laid in 1826 by Abel, whom Ostrogradsky may have met in Paris. From Ostrogradsky’s general results there follows the transcendency of a logarithmic function and of the arc tangent. " - The ostrogradsky method of integration
