Note 80 — NOTES.1

Claude Perrault (1613–1688) was a French physician and architect. He received his degree of doctor of medicine at Paris and practised medicine there. In 1673 he became a member of the Royal Academy of Sciences. Although he never abandoned his work in mathematics, in the natural sciences, and in medicine, he is more noted as an architect than as a physician or scientist. He was the architect of one of the colonnades of the Louvre, and of the Observatory.94
