When Mary Cassatt painted Eddy Cassatt (Edward Buchanan Cassatt) in 1875, she was not yet the celebrated Impressionist she would become, but a determined American artist forging her path in Paris. The sitter, her beloved younger brother, was a West Point cadet at the time, and this portrait stands as one of only a handful of images Cassatt made of her own family. The painting is also remarkable for its timing: created just before Cassatt’s decisive turn toward Impressionism, it captures her in a moment of transition, balancing academic rigor with the looser brushwork she would soon embrace. The portrait fixes the viewer’s gaze on young Edward, dressed in his military cadet uniform, his posture upright but his expression relaxed and introspective.

Cassatt chooses a moment of quiet dignity rather than martial bravado, emphasizing her brother’s individuality over his role as a soldier. The light falls gently across his face, highlighting the thoughtful set of his eyes and the softness of his features—details that speak to the artist’s affection and her interest in psychological depth. Unlike the more formal military portraits of the era, such as those by John Singer Sargent, Cassatt’s approach is intimate, almost familial, inviting the viewer to see not just the uniform but the young man within it. The exact medium of Eddy Cassatt (Edward Buchanan Cassatt) remains uncertain, as does much of its early history, but it is believed to have remained within the Cassatt family for many years.

The portrait holds a special place in Cassatt’s oeuvre, representing both a personal tribute and a record of her evolving style. Today, it is seen as a rare glimpse into the artist’s private world, predating her celebrated images of mothers and children. While the painting’s journey from Cassatt’s Paris studio to its current home is not fully documented, its survival offers a precious connection to the formative years of one of America’s most important painters.
