Consider for a moment the weight of silence. This Robert Keller Plaque commemorates not just a man, but an act of defiance. It honors Robert Keller, a French resistance fighter who paid the ultimate price for freedom.
This Robert Keller Plaque stands as a testament to courage. It also honors Laurent Matheron and Pierre Guillou, who worked alongside Keller. All three men were murdered in concentration camps. They represent countless others who resisted the Nazi occupation.
Robert Keller was an engineer with the PTT. The PTT was the French postal, telegraph, and telephone service. Keller used his position to gather intelligence for the Resistance.
In 1941, Keller joined the “Vengeance” movement. He helped gather information for London. He became a key figure in “Source K.” This was a clandestine operation to intercept German communications.
From April to December 1942, Keller and his team tapped into the German network. They listened to communications between Paris and Berlin. They targeted the Kriegsmarine, Luftwaffe, Wehrmacht, and Gestapo. The information they gathered was invaluable. It helped the Resistance and the Allies.
The “Source K” operation initially focused on 70 circuits. These ran on the Paris-Metz cable. It expanded to 484 circuits on the Paris-Strasbourg-Berlin cable. The operation was based in a villa in Noisy-le-Grand. Later, it moved to a house in Livry-Gargan.
Robert Keller’s team included engineers and agents. They risked their lives daily. They knew the consequences of discovery.
Sadly, their operation was compromised. An anonymous letter denounced Keller as a “Gaullist agent.” He was arrested on December 25, 1942. His team was dismantled.
Robert Keller was interned at Fresnes prison. On July 11, 1943, he was deported to Natzwiller-Struthof concentration camp. He was later transferred to Oranienburg-Sachsenhausen. Finally, he arrived at Bergen-Belsen. He died of typhus on April 14, 1945. This was just before the camp’s liberation.
After his death, Robert Keller was posthumously honored. He was named a knight of the Legion of Honor. He received the Croix de Guerre and the Medal of the Resistance. In 1957, a postage stamp was issued in his honor.
This Robert Keller Plaque serves as a reminder of his sacrifice. It is a tribute to his bravery and dedication.
The Robert Keller Telephone Center bears his name. This honors his service and memory. The city of Paris also named a street after him. It is a lasting tribute to a true hero.
Laurent Matheron and Pierre Guillou also have memorials. The Centre amplificateur de Rennes was named after Pierre Guillou. The centre de Lyon-Thassin was named after Laurent Matheron.
Let us remember Robert Keller, Laurent Matheron, and Pierre Guillou. They represent the spirit of resistance. They remind us that freedom is never free. Their courage continues to inspire us today.
