The English physician William Harvey (1578-1657) was the founder of modern
experimental physiology and the first to use quantitative methods to establish
verifiability in the natural sciences.
Born in Folkestone, Kent, on April 1, 1578, William Harvey came from a prosperous
family. After 6 years at King's School, Canterbury, he entered Caius College, Cambridge,
in 1593, indicating a preference for a medical career. When he was 20, he went to the
University of Padua, the center for western European medical instruction, where he
studied under the famed anatomist Fabricius of Aquapendente. In 1602 Harvey was
awarded degrees at Padua and at Cambridge.
Harvey was admitted as a candidate of the Royal College of Physicians of London in
1604, and that year married Elizabeth Browne, daughter of Lancelot Browne, physician to
King James I. In 1609 Harvey became physician to St. Bartholomew's Hospital, London,
and in 1616 he gave the first of his Lumleian Lectures before the Royal College of
Physicians, the manuscript notes of which contain the first account of blood circulation. In
1618 Harvey was appointed physician extraordinary to King James I.
Although Harvey's practice suffered because of his radical views, he was appointed
physician in ordinary to King Charles I in 1630, and in 1633 he was with Charles's court in
Scotland. Professionally, Harvey made news by examining and exonerating several
suspected witches and by performing a postmortem examination on Thomas Parr,
reputed to have lived 152 years. In 1642, the year he fled from London with the court,
he was made doctor of physic at Oxford. When his brothers died in 1643, Harvey retired
from St. Bartholomew's Hospital. In 1646 he fled with the court from Oxford back to
London and retired to live with his remaining brothers.
Harvey's great contribution, EXERCITATIO ANATOMICA DE MOTU CORDIS ET SANGUINIS IN ANIMALIBUS,
appeared in 1628. It was a poorly printed 72-page book, done by an obscure printer in
Frankfurt. Harvey probably arranged it this way in order to avoid trouble in England, for
he realized that his ideas flaunted the conventional teaching about the heart, which had
been derived from the writings of Galen. DE MOTU CORDIS was a landmark in the history of
science. In it Harvey demonstrated the circulation of blood in animals, thus giving a firm
foundation for the scientific development of the health professions. It must have been
composed at different times, for the introduction is more vigorous, and in its critical
attitude more youthful, than any of the rest of the 17 chapters.
Harvey's DE GENERATIONE (1651; ON THE GENERATION OF ANIMALS) pioneered modern
embryology and comparative sex psychology. This work was important in holding that the
embryo builds gradually from its parts, rather than existing preformed in the ovum. His
studies here were balked by the same difficulty which beset him in his studies on the
circulation: he had no microscope. He could neither demonstrate directly how blood would
move from arteries to veins, although he postulated the capillary anastomoses, nor
could he see directly how the embryo gradually aggregated. In most cases the
demonstration was completed by Marcello Malpighi, the great Italian biologist, who was
one of the first to have and use a microscope.
In 1653 appeared the first English edition of DE MOTU CORDIS, and Harvey's genius was
fully recognized. He gave buildings and a library to the Royal College of Physicians,
although he refused its presidency. He died of a stroke on June 3, 1657, and, "lapt in
lead," was buried in Hempstead church.
