Frédéric Houssay

Born in Dol-de-Bretagne on February 28, 1860, and later dying in Lyon on September 18, 1920, Frédéric Houssay was a French zoologist whose work moved between research, teaching, and popular science.

He studied at the École normale supérieure and went on to teach zoology in Paris. Sources also describe him as a professor at the Sorbonne and, near the end of his life, dean of the Faculty of Sciences in Paris. Alongside his academic career, he wrote books that opened zoology to a broader audience, including The Industries of Animals and La forme et la vie.

What stands out in his work is the way he linked the details of animal structure and behavior to larger questions about evolution and life itself. Even when writing for general readers, he treated zoology as something vivid and connected to everyday curiosity, which helps explain why his work still circulates in digital libraries today.
