Sarah Wilhelmina Wenzler (active 1861 – 1872) was an American painter of still lifes.
Little is known of Wenzler's life or career. She is known to have exhibited her still-life paintings at the National Academy of Design, the Boston Athenaeum, and the Pennsylvania Academy of the Fine Arts throughout the 1860s,[1] and she is recorded as having lived in New York City;[2] She is known to have specialized in depictions of hanging bunches of grapes.[3] One of these, Hanging Bunch of Grapes, an oil on canvas of 1867, is owned by the National Gallery of Art; it is signed "S. W. Wenzler".[4] Another of this painter's pieces, "Peaches and Pears on a Wooden Ledge", closed at Christie's on December 3, 2009 for $4780.[5] Few other paintings by Wenzler are known, and little else of her biography has been traced.[1]
