Civil rights activist Amelia Boynton Robinson died today at the age of 104. In 1965, she was beaten unconscious as she attempted to cross Selma’s Edmund Pettus Bridge on what became known as Bloody Sunday. Her voting rights activism began decades earlier in the 1930s.

“Amelia Boynton Robinson was a dedicated and courageous leader in the fight for civil rights. For most of her 104 years, Amelia committed herself to a simple, American principle: that everybody deserves the right to vote,” President Obama said in a statement today. “Fifty years ago, she marched in Selma, and the quiet heroism of those marchers helped pave the way for the landmark Voting Rights Act.”
