When the obligatory concession for his tomb in the cemetery of his native town of La Haye-Descartes was not renewed, Trouvé’s remains were thrown in to the common grave. His archives were destroyed in February 1980 during an accidental fire in the Town Hall.
In 2012, following a French biography by English transport historian Kevin Desmond, a commemorative plaque was officially unveiled on the site of his birthplace. Three years later, in 2015, following an extended English-language biography, a second plaque was unveiled on the wall outside his former workshop, 14 rue Vivienne, Paris 2ème.
The ongoing search for rare surviving examples of his instruments has now become worldwide.
