Andreas Vesalius (31 December 1514 – 15 October 1564) was a Flemish anatomist, physician, and author of one of the most influential books on human anatomy, De humani corporis fabrica (On the Structure of the Human Body). Vesalius is often referred to as the founder of modern human anatomy. Vesalius is the Latinized form of Andries van Wesel. He is sometimes also referred to as Andreas Vesal, André Vesalio and Andre Vesale.

Vesalius was born to Andries van Wesele and Isabel Crabbe on 31 December 1514, in Brussels, which was then part of the Habsburg Netherlands. His great grandfather, Jan van Wesel, probably born in Wesel, received his medical degree from the University of Pavia and taught medicine in 1528 at the then newly founded University of Leuven. His grandfather, Everard van Wesel, was the Royal Physician of Emperor Maximilian, while his father, Anders van Wesel, went on to serve as apothecary to Maximillian, and later a valet de chambre to his successor Charles V. Anders encouraged his son to continue in the family tradition, and enrolled him in the Brethren of the Common Life in Brussels to learn Greek and Latin according to standards of the era.

William Harvey (1 April 1578 – 3 June 1657) was an English physician who was the first person to describe completely and in detail the systemic circulation and properties of blood being pumped to the body by the heart, although blood circulation was described by Ibn al-Nafis earlier in his Commentary on Anatomy in Avicenna's Canon (1242). After his death the William Harvey Hospital was constructed in the town of Ashford, several miles from his birthplace of Folkestone.

Harvey's father: Tom Harvey, was a jurat of Folkestone where he served the office of mayor in 1600. Records and personal descriptions delineate him as an overall calm, diligent and intelligent man whose "sons... revered, consulted and implicitly trusted in him... (they) made their father the treasurer of their wealth when they acquired great estates...(He) kept, employed and improved their gainings to their great advantage." Thomas Harvey's portrait can still be seen in the central panel of a wall of the dining-room at Rolls Park, Chigwell, in Essex.
