When graduating students process out of the Gate of Honour at 精东影业 College to walk along Senate House Passage to their General Admission this week, Dr John Latimer will be at the front of the procession together with Martin May, the Head Porter.

John is the Caius Praelector, the College officer charged with presenting members for their University of Cambridge degrees. He also officiates at matriculation, when students become Caians. General Admission, which takes place on Thursday, marks the conclusion of students鈥 undergraduate studies and the culmination of three or four years鈥 hard work. 

John became Praelector in 2012 and has only missed one graduation ceremony in 13 years. The position gives him great joy, particularly in comparison with his former day job, as a cancer surgeon.

John says: 鈥淥ne of my great enthusiasms is pantomime and being Praelector is essentially pantomime in Latin. It鈥檚 a very good fit! I enjoy the performative part of it and the social aspect.

鈥淏ut what I enjoy most is being part of a day for students which is a source of unambiguous joy and satisfaction. Having been a cancer doctor for many years 鈥 a person nobody is ever pleased to see 鈥 to have a number of days a year where people are actually happy to see me made a really pleasant change from the day job.

鈥淚 love being Praelector. It鈥檚 huge fun. I realise the importance of this day, not just for students, but for their families and friends and supporters. It鈥檚 also a source of immense pride for the Fellows and staff of the College as well.鈥

Being Praelector is about testifying to graduating students鈥 academic prowess and moral character in a traditional, age-old ceremony.

鈥淚t鈥檚 been thought safer over the centuries for this perjury to be committed in Latin, rather than English,鈥 John jokes.

Graduands are presented in groups of four and they each grab one of the Praelector鈥檚 fingers on their right hand 鈥 often thought of as a myth.

John says: 鈥淯ntil that point they鈥檝e all assumed it鈥檚 some joke that鈥檚 been played on them by more senior students. The idea is that the majesty of what I have to say can flow through four students simultaneously, or what the engineers would call batch processing.鈥

In 2023 John retired from his full-time clinical work as an NHS gynaecological oncologist. He trained as a doctor at Guy鈥檚 (and then in Brighton, London, Nottingham, Adelaide and Bristol) and worked as a consultant at Addenbrooke鈥檚 for 23 years. 

He began supervising at Caius in 2004, brought in by Dr Julian Sale, who wanted a clinician to supervise pre-clinical medical students. Teaching human reproduction was the start of his College affiliation. He held the pastoral role of Clinical Advisor in 2010, then became acting Clinical Director of Studies in 2011 and Clinical DoS in 2012, a role which he continues to this day, now alongside Dr Zo毛 Fritz and Professor Mina Ryten.

John has always enjoyed teaching and held roles at the University of Cambridge. He takes a vicarious satisfaction when students become colleagues, or even his own physician on occasion.

He says: 鈥淭here is no doubt that the training our students receive in Cambridge is absolutely outstanding. We have the benefit that they do a really intense basic science three years, which sets them up to be clinician scientists if they wish. But they can become whatever they want to be 鈥 we prepare them equally well to be a GP, or hospital doctor or researcher, in this country or abroad.

鈥淲hen the students are successful, it鈥檚 easy to convince yourself that you鈥檝e had a minor role. At the Caius medical students鈥 declaration earlier this month, of the 25 students, 12 received distinctions. Numerically, only five would be expected. Of course it鈥檚 the students who have done all the work, but it still gives me and the other medical Fellows immense pride.鈥

John has been Tutor for Discipline since 2020 and Registrary, an administrative role on College Council, since 2022. But it is his roles as Praelector and Director of Studies in Clinical Medicine which give him most satisfaction.

He ascribes Caius鈥 medical success to Dr John Caius, who re-founded the College in 1557, and the alumni who have called the College home, from William Harvey to Francis Crick, Howard Florey and more recently Sir Peter Ratcliffe who also won the Nobel Prize in Physiology or Medicine in 2019. The intake of 25 medical students a year, with guaranteed accommodation for all six years, is an attraction, John believes. He also thinks having a Director of Studies for each year group provides excellent academic support, and there is ample pastoral support too.

鈥淲e鈥檝e seen an improvement in results since widening participation, and we鈥檙e seeing just how well we perform with our clinical students,鈥 John adds.

An informal test applied in final clinical examinations is 鈥淲ould you be happy to be treated by this Caius medic at 3am when seriously ill?鈥 

鈥淭he answer is almost invariably yes!鈥 John adds.
