Elizabeth Blackwell was the first woman to earn her medical degree​ in the United States​. Her sister Emily​ soon after​ followed in her footsteps. Janice Nimura tells the story of the "complicated, prickly" ​19th century ​trailblazers​ in her book 'The Doctors Blackwell.' ​"To me, [the Blackwells] taught me that it's really important in this moment to kind of relearn how to admire women​," Nimura says. ​ Also Ken Tucker reviews 'Peter Stampfel's 20th Century' a new collection from the folk musician.
