Marie Curie

French physicist Marie Curie (1867-1934) was one of many historical figures on the original 1893 expedition to Mars.

When the Avatar and company met her in Martian Dreams, Curie was living and working in the human settlement of Olympus. She quickly proved to be a storehouse of useful information about the radioactive element Radium, and had learned much about the habits of the rockworms that dwelt near it. From her room, the Avatar was able to obtain a lead box and a set of tongs, with which to safely handle and store any radium they acquired in the future.

Curie returned to Earth in the Space Cannon once the group's adventures on Mars were over.
