The Warren Anatomical Museum at the Harvard Medical School was founded in 1847 by John Collins Murray with the aim of teaching students about human anatomy. Today, Harvard's Center for the History of Medicine has made a number of items featured in the museum available through this online exhibit. This collection includes illustration lithographer Oscar Wallis, who was commissioned by surgery professor Henry Jacob Bigelow to create a number of works for the school between 1848 and 1854. In addition, the collection features work by William Jurian Kaula, who is also known for his landscape paintings. In this exhibit, visitors can read more about Wallis and Kaula and look at a number of their medical illustrations. These illustrations are organized into categories, which include diagrams, surgical procedures, microscopic views, bones, and digestive tract. Collectively, these items offer insight into nineteenth-century medical practice and the intersections of art and science.
