Christopher Wren begain training at the age of 15 as an anatomical assistant to his personal physician Sir Charles Scarburgh who was a student and favorite of William Harvey. At Oxford, the teenaged Wren, together with Richard Lower, performed experiments involving the injection of substances into the vein of dogs (documented in a letter by Robert Boyle) and injected dyes in the cerebral vessels of post-mortem human material leading to the description of the aarterial circulation bearing the eponym fo Sir Thomas Willis. The illustration of the base of the human brain introduced the then new mezzotint engraving technique to anatomical illustration and provided the first clear depiction of the arterial 'circle of Willis' which apeared in Sir Thomas Willis' Cerebri Anatome of 1664. The 'great fire' of London that year diverted the young Wren to the royal request of devising a new plan for the 'city' of London and the reconstruction of the world's largest cathedral, St. Paul's, thus beginning the next plase in the artistic career of Wren who became England's most distinguished and prolific architiect. Sir Christopher Wren subsequently was elected President of the Royal Society and it is in recognition of his contribution to science and architechture, that the logo design and architecture of this website is dedicated to his name.
