Both the fitness and the socializing were part of the new activities she began to engage in after years of devoting herself to the care of her ailing husband, they said.
At about 10:30 a.m. on Wednesday, Montgomery County police said Cohen had left an LA Fitness and was trying to cross Copley Place toward a nearby Starbucks when she was struck.
Police said the vehicle that hit her was trying to turn left onto Copley after leaving a grocery store parking lot.
Cohen died Monday at a hospital. The police said they are continuing to investigate the collision.
Family members said Cohen had been in a water aerobics program that, along with the people she met while taking part, helped Cohen renew herself after the death of her husband six years ago.
A son, Andrew, said his mother started a group called the “Tuesday Tootsies.” “You had to be a widow to get in,” he said.
Eleanor Cohen had spent 55 years with her husband, her sons said. The couple had eloped when she was 17 and a freshman at New York University and they had lived in northern New Jersey and Richmond before coming to this area about 15 years ago, her sons said.
