Summary
editDescriptionPortrait LG PERREAUX.jpg |
Français : Ce portrait mérite quelques explications. En effet en dépit de recherches qui débutent dès les années 1920 aucun portrait de L.G. Perreaux n’a pu être identifié à ce jour. Depuis nous savons par les archives de l’École des Arts et Métiers de Chalons en Champagne que L.G. Perreaux avait le visage défiguré par la variole et il est logiquement fort probable que L.G. Perreaux ne tenait pas à être portraituré. Ce portrait au crayon n’est donc qu’une œuvre d’artiste ayant eu pour modèle l’autoportrait de L.G. Perreaux placé dans sa peinture illustrant son ouvrage Lois de l’Univers. Portrait validé par le Conseil Départemental de l'Orne, le magazine Arts et Métiers (Arts et Métiers Mag Février 2018 n°397) et le site Futura Sciences. |
