Sir St Clair Thomson gave his lecture in 1935 and focused on the different modes of defence against respiratory microbial germs. The talk aimed to show the complexity and perfection of these defences, their mode of action and their reciprocal reaction and demonstrate the interest of knowledge of natural processes as a necessary preliminary to the study of disease.
St Clair Thomson was born on the 28th of July 1859 in Londonderry, Ireland. During his career, he spent time as throat physician to King Edward VII, a tribute to his status as a renowned laryngologist. He acquired a number of titles and roles throughout his career, one of which was as President of the Royal Society of Medicine between 1925-1927.
