Professor Arjen Dondorp
Christine Stabell Benn, MD, PhD, DMSc, MAE, has worked at the Bandim Health Project in Guinea-Bissau since 1993. Dr. Benn holds a position as a Professor of Global Health at University of Southern Denmark. She is also a Chair at the Danish Institute for Advanced Study.
“I am very happy and honoured to be awarded the George Macdonald Medal. There are many assumptions about which interventions work in low- and middle-income countries and many assumptions about how the interventions work. My group has made it a top priority to challenge these assumptions in global health, by assessing the overall health effects of interventions in real life settings. The medal is a great encouragement to continue this line of curiosity-driven research.”

History and prize

Professor George Macdonald
The George Macdonald Medal was first awarded in 1972 in honour of Dr George Macdonald, Professor of Tropical Hygiene at the London School of Hygiene & Tropical Medicine and Director of the Ross Institute, who died on 10 December 1967.
A dominant figure in the field of tropical public health and one of the world's great authorities of malariology, George Macdonald distinguished himself by his work on quantitative analysis of the transmission and eradication of vector-borne tropical diseases.
His personality combined great intellectual power, fearless integrity, tremendous energy and an understanding of human problems.
In October 1968, the Dean of the London School of Hygiene & Tropical Medicine, launched an appeal for an endowment of a permanent memorial to Professor Macdonald in the form of a medal to be awarded in recognition of outstanding contributions to tropical hygiene. Many of Professor Macdonald's friends and colleagues all over the world responded generously to this appeal.
The medal bears on its obverse a likeness of Professor Macdonald with the inscription "Professor George Macdonald 1903-67" and on the reverse the words "For services to tropical hygiene".
