William Cowper
William Cowper (1666 – 1710). English barber-surgeon and anatomist, William Cowper (sometimes known as William Cooper) was born in Petersfield, Hampshire. After apprenticeship with famous barber-surgeons, Cowmper was admitted as a Freeman to the Company of Barber Surgeons in 1691 after which he had a successful career as a surgeon and an anatomist in London.
Cowper opened the first private school of anatomy in London. In 1694, Cowper published “Myotomia Reformata “, a great textbook with a description of all the muscles. A controversy arose because Cowper used the illustrations from another book by Govert Bidloo (1649 – 1713). The controversy became a problem for Cowper who had to answer questions on the subject to the Royal academy, where Cowper became a member in 1699. Cowper alleged that Bidloo’s plates, although greatly illustrated had a poor description which he improved.
In 1699 Cowper published the “Philosophical Transactions” where he describes the bulbourethral glands which are today eponymically tied to his name. An infection of these glands is called a “Cowperitis”.
The bulbourethral glands had already been described by Jean M?ry (1645– 1722) and Cowper did not claim to discover these glands. As in the case with many eponyms, the name attached to a structure is not necessarily the one who discovered it. Today, many do not remember that Cowper's name is also used to describe "Cowper's ligament", that portion of the fascia lata that is attached to the iliac crest.
