SANDWICHED IN: I Can’t Die But Once: The Life of Harriet Tubman. Harriet Tubman is best known for her role as a conductor on the Underground Railroad. She has been immortalized in the minds of Americans for 130 years. Though she is one of the most famous women in our nation’s history, we have come to know her life only through fictionalized biographies written for school children. The reality of Harriet Tubman’s life is far more compelling. Gwendolyn Quezaire-Presutti reveals the true story and separates reality from myth to reconstruct a richer and far more accurate historical account of her life. 12:10 p.m.
