Merio Ameglio was born in 1897 in San Remo, Italy. After his formative years of painting along the French coast, Ameglio moved to Paris in 1938 where he continued to explore and perfect his artistic abilities. Montmartre became not only his main residence but also the beginning of his cultural awakening. Although considered to be self taught, his formal education was provided through his encounters and friendships with Pablo Picasso, Jacques Villon, Gino Severini, Van Dongen and Jean Paul Francois Galle. Ameglio established his atelier within walking distance of the heart of Montmartre.

Ameglio became a member of the Paris Salons and exhibited regularly there. In 1938, during the International Art Exposition, he won considerable acclaim and was awarded his first honorable mention for the painting "Cathedrale de Rouen". In 1969 a retrospective exhibition of his work was held at the Galerie Cambaceres in Paris. His work can be found in numerous private and public collections worldwide
