Oh yes, and Robert Hooke
He was John Adams to Newton's Thomas Jefferson: The man lacked the charisma
and cronies that Newton had, but he came up with quite a few amazing discoveries
of his own.
Netwon himself, his followers, and those who "worshipped" him afterwards
were the ones who downplayed Hooke and every other just as smart fellow who had
their own great ideas at the same time, which is why you hear so much about the
falling apple guy and far less about his contemporaries.
