On August 18, 2020, The United States will celebrate the 100th anniversary of the ratification of the 19th Amendment which gave women the vote. Belle La Follette played an important role in helping women gain the right to vote guaranteed in this amendment. She advocated for women in her home state of Wisconsin and across the country. This article describes a lesson that used the C3 Framework and Inquiry Design Model (IDM) to assist teachers in creating a student driven lesson that used primary sources to study how an individual with many strengths and a few human flaws created social changes. Certainly, Belle is not the only leader who is worthy of in-depth study. This inquiry lesson can be replicated to conduct student research about significant, but unrecognized, historical figures from all time periods and geographic locations. The students showed they were capable of a rigorous study of the accomplishments and tribulations of a significant historical figure.
