On February 27, 1947, Deputy Louis Marin made a brief reference to the research work carried out by Louis Rota during a long speech to the National Assembly.
Excerpt from the speech of Louis Marin
On the eve of 1939, we were on the point, in a laboratory in Saint Aignan, of discovering the means of stopping the engines remotely. I also hope that the progress of this work has not been stopped.
It's a simple sentence, but meaningful because of the personality of the speaker.
Louis Marin was an experienced politician, minister of state several times during his long career. Dismissed from the government in 1940 following his opposition to Marshal Pétain, he remained in France and joined the Resistance. Exfiltrated to London in 1944, he became a member of the Provisional Consultative Assembly, then of the two Constituent Assemblies and was elected, in 1946, at to the first National Assembly of the Fourth Republic.
The professional career, the personality of Louis Martin allow us to suppose that the allusion to the laboratory of Louis Rota was not a simple oratorical effect.
There must certainly be documents in the military archives that could shed light on Louis Rota's work.
