[1] He was educated at the School of Mines in Liège, where he learned how to quarry and polish stone for sculptures, as well as the technical process for creating photographic toning agents from minerals.

After graduation, he moved to Paris, France, to work at Maison Walery as a photograph technician, but he sculpted in his free time.

Under the advice of his wife, the couple moved to New York City, where they established a photography studio in Harlem, with Etta handling the finances so that Dupont could focus on the art.

This proved to be so successful that in 1886 they moved the studio to 574 Fifth Avenue in Midtown Manhattan and he soon became the official photographer for the recently formed Metropolitan Opera.

[7] Afterwards, Etta became the photographer for the business (and in later years, their son Albert also took his turn behind the camera), keeping the name Aimé Dupont Studio.

However, in 1906 the Metropolitan Opera, the studio's primary client, hired its own photographer, and without the artistic direction of Dupont, the business began to suffer.
