On October 24, 1972, the first African-American to play Major League Baseball, Jackie Robinson, died at the age of 53 in Stamford, Connecticut. On the same day in 2005, Rosa Parks passed away in Detroit at the age of 92. Parks inspired the Montgomery Bus Boycott when she was arrested for refusing to give up her seat on the bus to a white man in Montgomery, Alabama. Both Parks and Robinson were symbols of the civil rights movement, which led to the passage of the Civil Rights Act and the Voting Rights Act.
