Vintage photos show the unsung heroes of the US suffrage movement

At Washington’s National Portrait Gallery, the centennial of the 19th Amendment, which gave men and women equal voting rights, is being marked by “Votes for Women: A Portrait of Persistence,” a comprehensive exhibition that highlights the key figures and moments in the decades-long fight for women’s voting rights.

Originally set to open on March 1 (it was delayed by the recent government shutdown, which shuttered the Smithsonian network of museums), the exhibition tells part of the complex story of how we reached where we are today, throwing into relief the struggle for women’s suffrage and the place of women’s voices within the politics of the last century.
