When Edgar Degas painted his younger brother Achille in 1856, he was just twenty-one and still years away from the innovations that would make him famous. This is the earliest known portrait by Degas of a member of his own family, and it marks the beginning of a lifelong fascination with capturing those closest to him. The painting is also remarkable for its subject: Achille, aged fifteen, had just entered the Lycée Louis-le-Grand as a cadet, a moment of pride for the bourgeois De Gas family.

Decades later, Achille would become a recurring figure in Degas’s sketches and paintings, but never again with such youthful formality. The portrait fixes Achille at the threshold between boyhood and adulthood, his cadet’s uniform crisp and his posture upright, yet his gaze betrays a hint of unease. Degas chooses to show his brother not in action, but in a moment of stillness—his hands resting, his face set in a quiet seriousness. The dark, subdued palette and simple background focus all attention on Achille’s expression and the gleaming buttons of his uniform, symbols of discipline and social aspiration.

Unlike the grand, heroic portraits of military youths by Ingres, Degas’s approach is intimate and unsentimental, emphasizing psychological presence over public display. The painting’s early history is little documented, but it likely remained in the De Gas family for many years, treasured as a private keepsake rather than a work for public exhibition. As Degas’s reputation grew, this portrait gained new significance, offering a glimpse into his formative years and the personal world that shaped his art. Today, Achille De Gas in the Uniform of a Cadet is recognized as a rare surviving example of Degas’s early portraiture, and it is held in the Musée d’Orsay, Paris.

It stands as a testament to the artist’s roots in tradition, before he turned his gaze to the ballet studios and boulevards of modern life.
