There are only four elements that were named after actual scientists.
Curium [Cm] is named after Marie and Pierre Curie. The Curies worked extensively on radioactive elements so another scientist appropriately named this radioactive element after them.
Einsteinium [Es] is named after the famed physicist Albert Einstein.
Lawrencium [Lr or Lw] is named after Ernest Lawrence, who invented a machine to detect radioactivity. Lawrencium is a radioactive element. Mendelevium [Md] is named after Dimitri Mendeleef who created the modern day periodic table.
