18th March

On this day in 1649, Christopher Wren received his BA degree from Oxford. He was elected a Fellow of All Souls, Oxford, two years later and lived in the College until 1657. At Oxford Wren carried out many scientific experiments. He worked on anatomy, making drawings of the human brain for Willis's Cerebri anatome and he devised a blood transfusion method which he demonstrated by transfusing blood from one dog to another.
