What elements are named after scientist?
Quite a few are.
Curium, einsteinium, fermium, mendelevium, nobelium, lawrencium
(maybe), rutherfordium, seaborgium, bohrium, meitnerium,
roentgenium, and copernicium are all named after scientists.
I'm not sure what you consider "famous". It's perhaps excusable
not to know who Ernest Lawrence, Glenn Seaborg, and Lise Meitner
were (even though two of them won Nobel prizes and the third should
have), but anyone with any degree of knowledge of the history of
science should recognize the others.
Lawrencium is a special case. It was discovered at the Lawrence
Radiation Laboratory, so whether it's "really" named after Lawrence
or named after the laboratory itself is kind of an open question.
However, the reason the lab was called that was because of Ernest
Lawrence, so either directly or indirectly it's named after
him.
There's also berkelium, which is indirectly named after George
Berkeley (it's named after a city that's named after him), who was
a philosopher at a time when "philosopher" and "scientist" were
regarded as more or less the same thing. (Not-so-incidentally, the
Lawrence Radiation Laboratory is associated with the University of
California - Berkeley and is now known as the Lawrence Berkeley
National Laboratory. Guess where berkelium was discovered.)
