Robert Hooke: Early Respiratory Physiologist, Polymath, and Mechanical Genius

Abstract

Robert Hooke (1635–1703) was a polymath who made important contributions to respiratory physiology and many other scientific areas. With Robert Boyle, he constructed the first air pump that allowed measurements on small animals at a reduced atmospheric pressure and this started the discipline of high altitude physiology. He also built the first human low pressure chamber and described his experiences when the pressure was reduced to the equivalent of an altitude of about 2400 m. Using artificial ventilation in an animal preparation he demonstrated that movement of the lung was not essential for life. His book Micrographia describing early studies with a microscope remains a classic. He produced an exquisite drawing of the head of a fly showing the elaborate compound eye. There is also a detailed drawing of a flea, and Hooke noted how the long, many-jointed legs enable the insect to jump so high. For 40 years he was the curator of experiments for the newly founded Royal Society in London and contributed greatly to its intellectual ferment. His mechanical inventions covered an enormous range including the watch spring, wheel barometer and the universal joint. Following the Great Fire of London in 1666 he designed many of the new buildings in conjunction with Christopher Wren. Unfortunately Hooke had an abrasive personality which was partly responsible for a lack of recognition of his work for many years. However during the last 25 years there has been renewed interest and he is now recognized as a brilliant scientist and innovator.
