For centuries, scientists believed that living matter possessed a special quality—a spirit or essence—that differentiated it from nonliving matter. But by the nineteenth century, the scientific consensus was that the building blocks of one were identical to the building blocks of the other. Elixir tells the story of two young chemists who were not convinced, and how their work rewrote the boundary between life and nonlife.

Augustin Fresnel (1788–1827) shocked the scientific elite with his unique understanding of the physics of light. The lens he invented was a brilliant feat of engineering that made lighthouses blaze many times brighter, farther, and more efficiently. Battling the establishment, his own poor health, and the limited technology of the time, Fresnel was able to achieve his goal of illuminating the entire French coast. At first, the British sought to outdo the new Fresnel-equipped lighthouses as a matter of national pride.

 Elixir tells the story of Edouard Laugier and Auguste Laurent, the son of a perfumer and a fellow aspiring chemist, who met on the Left Bank while pursuing their passion for science. Spurned by the scientific establishment, the pair ended up working out of Edouard's family perfume shop, Laugier père et fils. By day they prepared the revitalizing elixirs and rejuvenating eaux it was famous for, but by night using the ingredients of the perfumery and the principles of alchemy, they pursued the secret of life itself.
