Sir Rickard Christophers Medal Winners Webinar

History and prize

Sir Rickard Christophers was President of the Society between 1939 and 1943.

From 1898, when he was appointed member of the Malaria Commission of the Royal Society, to 30 years working in India and another three decades of work in London and Cambridge, Sir Rickard's contribution to many branches of medical and other sciences was immense.

The impact of his studies on malariology and entomology was deep and lasting; his fundamental investigations of the pathology, immunology, epidemiology and control of insect-borne diseases made him a true "compleat scientist" of our age.

Sir Rickard died in 1978, aged 104, after a lifetime spent in the relentless and inspired pursuit of knowledge. 

The Royal Society of Tropical Medicine and Hygiene decided to commemorate the life and achievements of Sir Rickard by endowing a medal.

The Sir Rickard Christophers Medal is awarded for work in tropical medicine and hygiene in its broadest sense and in particular for practical and field applications.

The medal, which is in bronze, bears the likeness of Sir Rickard on the obverse and on the reverse bears a geographical representation of the tropics with the Society's motto Zonae torridae tutamen.
