Ranked first in his class 2 years later, he received the first Laplace Prize, a copy of the astronomer's complete works that is said to have prompted his interest in celestial mechanics. After turning down an offer from Dominique Arago to join the Paris Observatory after his mentor Félix Savary, from the Bureau des longitudes, said that this amounted to forfeiting his independence, Delaunay attended the École des mines, with which he stayed closely associated through the early part of his career.
