Artistic muse
John Singer Sargent, the famed portraitist of Boston's elite, was commissioned by Warren's husband, Fiske Warren to paint her portrait in April 1903.[4] The sitting was done in Fenway Court, then the home of legendary Boston fine arts czar; Isabella Stewart Gardner. Warren is seen seated in a chair with her daughter, Rachel Warren. The painting is often considered to be one of Sargent's prime portraits and usually appears in Sargent Estate calendars and postcards.[5][6][7] Later she was also photographed by portrait photographer Arnold Genthe.[8]
