Friedman and her husband, Arthur, championed the historic designation of Greenbelt Knoll, regarded as the nation's first planned racially-integrated housing development, and succeeded when it was listed as a historic district on the Philadelphia Register of Historic Places in 2006.
The community is marked with a plaque installed by the Pennsylvania Historical and Museum Commission.
A native of Harrisburg, Friedman relocated to Philadelphia to attend the Albert Einstein Hospital School of Nursing following her graduation from William Penn High School in 1954. She graduated from Einstein three years later and worked as a registered nurse before retiring to raise her family.
An avid gardener, she was active in community work in Greenbelt Knoll.
In addition to her husband, Friedman is survived by daughters Caren Friedman and Jorey Friedman; son Paul Corky Friedman; and a grandson.
