'From Felix to the helix, and from the cradle to the grave - Semon's contribution to thyroid surgery', Royal Society of Medicine, 1 November 2019, London, UK.

Mr President, Mr President Elect, Fellows and Members, Ladies and Gentleman, it is a pleasure to address the Section of Laryngology this morning and deliver the 94th Semon Lecture. I would like to thank the Semon Committee for their kind invitation. My lecture will discuss Sir Felix Semon (the man himself), highlight the history of head and neck surgery, and then discuss the requirements of a modern-day thyroid surgeon. I have no conflict of interest and nothing to declare.
