CHICAGO (CBS) — On what would have been Civil Rights icon Emmett Till’s 80th birthday, his childhood home in Chicago’s West Woodlawn neighborhood got a historic landmark plaque Sunday.

City officials on Sunday presented the plaque outside the home at 64th Street and St. Lawrence Avenue.

The plaque recognizes Till and his mother, Mamie Till-Mobley, as key figures in Great Migration history.

Till was just 14 years old when he was kidnapped, beaten, and lynched after being accused of whistling at a white woman while visiting Money, Mississippi in 1955.

It was the days and years that would follow that served as a catalyst in the civil rights movement.

Earlier this year, the home where Till grew up in officially became a city landmark.

The nonprofit Blacks in Green recently bought the house. The organization plans to convert the home into a museum and community theater.

The murdered teenager is buried alongside mother Mamie Till and her husband Gene Mobley.
