Fourier’s personal heat problem

Joseph Fourier is perhaps best known for his work studying heat conduction. He developed what we now call Fourier series as part of this work.

I recently learned that Fourier had a personal problem with heat.

Even though Fourier conducted foundational work on heat transfer, he was never good at regulating his own heat. He was always so cold, even in the summer, that he wore several large overcoats.
