Mr William Mayhew Mollison delivered his Semon Lecture in 1938. He discussed the various groups of Streptococcus and reviewed the factors that influence immunity and resistance. He then went on to describe the origins of the infection and the various sources of infection and modes, before looking at prophylaxis.
William Mollison was born on the 20th of December 1878 in England. He had a highly successful career, which included successes such as his time as President of both the Laryngology and Otology Sections of the Royal Society of Medicine. As well as the paid work he carried out, he also volunteered and received a C.B.E for his voluntary contributions to St. Dunstan’s.
