Essie, Ruby and Ferdinand, Children of Asher Wertheimer

Asher Wertheimer was Sargent's most important patron in Britain, a London art dealer who commissioned over ten family portraits from the artist between 1898 and 1908 — one of the most sustained portrait series in the history of British painting. This 1902 canvas depicting three of his children — Essie, Ruby, and Ferdinand — is notable for its informal, affectionate character: the children depicted in natural poses suggesting a happy, prosperous family life rather than formal status display. Wertheimer eventually bequeathed the entire portrait series to the nation; they now hang at Tate Britain.

Sargent arranges the three children in a loose, triangular grouping that conveys familial warmth without stiffness. His brushwork is at its most spontaneous — swift, confident, building each figure from broad washes and precise accents. The palette is warm and luminous; background is simple and dark.
