The Bigelow-Wallis and Warren-Kaula watercolor collection is a series of works in Warren Anatomical Museum originally compiled by the Harvard Medical School Department of Anatomy for use in the anatomical lecture hall. The average size of the watercolors is 69 cm wide x 100 cm high and the works are mounted with metal grommets in the corners for hanging. The bulk of the collection is the 189 works commissioned by Harvard Medical School Professor of Surgery Henry Jacob Bigelow from lithographer Oscar Wallis between 1849 and 1854. The remaining 46 watercolors in the collection were painted circa 1894 by William Jurian Kaula for Harvard Medical School Moseley Professor of Surgery John Collins Warren. The Department of Anatomy combined the two physician-artist collaborations into one teaching series within the Warren Anatomical Museum in the early 20th century.
