The photographer Louis Daguerre died in Bry-sur-Marne in 1851 and a monument marks his grave there.
In 1903, archeologist Adrien Mentienne uncovered the bones of a large bovine which died 15,000 years ago. In 1982, the skeleton of a woman who died in the 5th century BC was uncovered beneath the playground of a school in Bry. It is now housed in the town's museum
From that century onwards, there was a permanent human presence where Bry now stands. In 1886, a necropolis was found which contained pottery, Gaul and Frankish weaponry, silver and gold jewelry, and coins, dating from the Gaul era to the Merovingian. The first known written mention of the town named Bry was in a charter signed by King Charles the Bald in 861.
The first church was built in 1130.
The railway came to Bry in 1926, followed by the motorway (1970) and the RER (1977). The town's hospital was built in 1936 .
