LEGENDRE, Mémoire sur les transcendantes elliptiques, 1793

First edition.
Work which proposes a classification and reduction of elliptic functions with a view to obtaining a general algorithm for their processing.
Leonhard Euler, Legendre's revered master, had studied elliptic integrals and his work served as his starting point. Legendre therefore immersed himself in research on elliptic integrals and, in 1792, presented to the Academy his Mémoire sur les transcendantes elliptiques, which the institution took a year to publish.
This work will serve as a starting point for Niels Abel's research on elliptic functions.

Legendre's work is bound after that of Cousin:
