The former attorney died Wednesday at the age of 90.
St. Sabina pastor Father Michael Pfleger joined the tribute.
Langford was the first black woman to serve in the city council. Her son, Fire Department spokesperson Larry Langford, was asked how to remember her.
"As someone who saw things wrong, and did the best she could to make them right. And she walked the walk, and talked the talk. She stayed right here in Englewood her entire adult life. And she worked to make conditions better in Chicago and everyplace she went," said Larry Langford.
Anna Langford was elected an alderman in 1971, and served three terms.
