Mamie Elizabeth Till-Mobley (born Mamie Elizabeth Carthan; November 23, 1921 – January 6, 2003) was born in Webb Mississippi. She was an American educator and activist. She was the mother of Emmett Till, who was murdered in Mississippi on August 28, 1955, aged 14, after allegedly interacting "inappropriately" with Carolyn Bryant, a white cashier at the grocery store. For her son's funeral in Chicago, Mamie Till insisted that the casket containing his body be left open. She became a teacher, changed her surname to Till-Mobley, and continued her life as an activist working to educate people about what happened to her son. She worked throughout her life to help children living in poverty. She spent 23 years teaching in the Chicago public school system. She established a group called "The Emmett Till Players," which worked with school children outside of the classroom. The members learned and performed famous speeches by civil rights leaders such as Martin Luther King Jr. She also spent a great deal of time contributing to knowledge production.
