Samuel Ernest Whitnall (March 30th, 1876-February 19, 1950) was an English doctor, anatomist and humorist. He is known for his work on orbital anatomy, having described the Whitnall ligament and the Whitnall tubercle. He was also distinguished for writing one of only known examples from the era of a parody of medical guides for students.
Whitnall earned his doctorate at Oxford. He worked there from 1908-1919 as demonstrator of anatomy, eventually joining the Royal College of Physicians, London. He later taught at McGill University as a professor of anatomy.
