my research, I've found the
following about the origin of
the word feminism:
The term was coined in France--feminisme--in
the 1880s by Hubertine Auclert,
a key figure in France's suffrage
movement. It first appeared
in the U.S. in an article from
1906--discussing Madeleine Pelletier,
another woman active in the
European Woman's Suffrage movement.
The above information is from
Imagine Change: Women's Writings
600 BCE to the Present--and
specifically from research done
by the academic Nancy Cott.
I hope that helps.
