Amellér was born in Arnaville, Meurthe et Moselle) to a family of amateur musicians. He began studying violin at a young age in the family's home in Chelles. He later began playing double bass. In January 1930, he joined the 24th Infantry Regiment of the French Army, playing in the regiment band.
While still a soldier, Amellér began his studies at the Conservatoire National Supérieur de Paris in 1931 under Édouard Nanny. He played for Concerts Poulet in 1932, then joined the Pasdeloup orchestra. He appeared as a soldier in the film "Les croix de Bois", and used the money from that role to buy his first double bass. In 1934, he graduated with honours from the Paris Conservatory with a degree in double bass. Between 1934 and 1947, he also received degrees in conducting, harmony, fugue, counterpoint, composition and music history.
In 1937, Amellér won a position as double bassist in the Opéra national de Paris. He played under conductors Bruno Walter, Arturo Toscanini, Wilhelm Furtwängler, Albert Wolff and Paul Paray. When France entered World War II, his regiment was mobilized; he was taken prisoner and spent time as a prisoner of war in Oflag XIII. After being liberated, he returned to his position in the Opéra national in 1942.
