Thomas Willis

Willis’ first marriage was to clergyman Samuel Fell’s daughter Mary and the couple had nine children of whom one died in infancy. Upon Mary’s demise, Thomas entered the wedlock with Elizabeth Calley in 1672.

The eminent scientist breathed his last on November 11, 1675 in London.

Thomas Willis was born on January 27, 1621 in the Great Bedwyn village of the Wiltshire County in England. His father worked as a stewardess for the baronetcy of the Willys of Fen Ditton.

He studied at the ‘Christ Church’ college affiliated to the ‘Oxford University’ and completed his bachelor’s degree in arts 1639 and then obtained a master’s degree three years later.

He then went on to study medicine and received a bachelor’s degree in medicine after successfully completing the course in 1646.

Thomas started his medical practice in the market town of Abingdon and in the year 1656 he penned his first work on medicine, titled ‘De Fermentatione’. It was followed by another significant composition ‘De Febribus’ that was published three years later. It was during this time that natural philosopher Robert Hooke assisted him.

He was appointed as the ‘Sedleian Professor of Natural Philosophy’, at the ‘Mathematical Institute’ of ‘Oxford University’, in 1600, a position he would hold for the rest of his life. He became a member of the newly-founded ‘Royal Society of London’ the following year.

In 1663, he penned another book ‘Diatribae duae medico-philosophicae – quarum prior agit de fermentatione’. The following year one of his major works on anatomy of human brain ‘Cerebri anatome’ was published. The diagrams for the book were provided by Christopher Wren and the book contained many significant observations made by Willis.

He established his practice in the Westminster city of London starting in 1666. As a physician he used to combine his knowledge of human anatomy with the general remedial measures for treating his patients.

Willis’ most significant contribution towards understanding of the anatomy of human brain was his discovery of the ‘Circle of Willis’, which is a connection between arteries that are responsible for supplying blood to the brain.

Willis’ most important contribution, in the field of medicine, were his works on the anatomy of human mind. He provided detailed and precise description of the structure and function of various important sections of the brain such as the cranial nerves and cerebellum. His observations were quite pronounced in comparison to the works of his predecessors.
