Haávers /'hA-v&rz, 'hav-&rz/, Clopton (1655?–1702), British osteologist. In 1691 Havers published thefirst detailed description of the microscopic structure of the bone lamellae and canals and made important observations on the physiology of bone growth and repair. Although Antoni van Leeuwenhoek hadobserved the haversian canals in 1686, and Malpighi had mentioned the bone lamellae in 1675, Havers' work is remembered particularly because of its full and systematic treatment.
