The son of a London rabbi, whose body was never found after the First World War, was one of thousands of lost soldiers remembered at the 90th anniversary of the Unknown Warrior this week.
AJEX attended the Western Front Association's commemoration ceremony on Wednesday on Platform Eight of London's Victoria station - where the original "unknown soldier" arrived in November 1920 before being laid to rest in Westminster Abbey.
More than 20,000 Jewish servicemen died in the First World War, and many bodies were never recovered. One of those posted as missing was Lieutenant Leonard Herman Stern, 24, son of Rev Joseph Frederick Stern of East London Synagogue. He was believed to have died in May 1915.
AJEX's Jeff Borsack said: "It would be ironic if the Unknown Warrior in Westminster Abbey was a Jewish man.
"But so many Jews volunteered to fight, and died in their thousands. That's why we are here, to show how much Jews have given to this country and how they continue to serve in the British armed forces today."
This weekend and next, AJEX members will take part in remembrance parades all over the country.
