Everyone recognizes this picture. It is Marie Curie! The problem though, it's not her. Instead, it is a photo of Susan Marie Frontczak, snapped by Paul Schroder in 2001.

Frontczak makes a living portraying the famous scientist on stage, and has done so for 13 years. The image (of Frontczak) can be found on "Marie Curie"-themed stamps in Mali, the Republic of Togo, Zambia, and the Republic of Guinea.

This is image below, however, is the real Marie Curie, Frontczak modeled after.
