Stylized blueprint portrait of Claude-Louis Navier

Claude-Louis Navier

1785 – 1836

Turned beam theory into engineering design and co-founded fluid mechanics.

A French engineer who turned beam theory into practical design formulas in the 1820s and co-founded fluid mechanics — the Navier–Stokes equations bear his name. He effectively founded structural engineering as a taught discipline.

The beam, structural, and pipe-flow tools here descend from Navier's work bridging pure mechanics and the drawing board.
