Lagrange and Laplace -> Poisson -> Michel Chasles -> Jean-Gaston Darboux -> Émile Borel -> Georges Valiron -> Laurent Schwarz -> Jacques-Louis Lions -> Haïm Br

Lagrange and Laplace -> Poisson -> Michel Chasles -> Jean-Gaston Darboux -> Émile Borel -> Georges Valiron -> Laurent Schwarz -> Jacques-Louis Lions -> Haïm Brezis -> Pierre-Louis Lions -> Cédric Villani Lagrange also advised Fourier, Schwartz also advised Grothendieck, Borel also advised Lebesgue etc... Lagrange was advised by Euler, and Laplace by D'Alembert So another path is Euler -> Lagrange -> Fourier -> Navier another one: D'Alembert -> Laplace -> Poisson -> Dirichlet -> Lipschitz -> Felix Klein -> Lindemann -> Hilbert etc etc
