List of names on the Eiffel Tower
On the Eiffel Tower, 72 names of French male scientists, engineers, and mathematicians are engraved in recognition of their contributions. Gustave Eiffel chose this "invocation of science" because of his concern over the protests against the tower, and chose names of those who had distinguished themselves since 1789.
