After attending the Dragon School in Oxford and Westminister School in London, Marsh studied Politics, Philosophy and Economics at Oxford University. He graduated with a First Class Honours Degree before attending the Royal Free Medical School to study Medicine.
Henry joined the Royal College of Surgeons in 1984 and was appointed senior consultant neurosurgeon at the country’s largest specialist brain surgery units at St George’s Hospital, South London until 2015. Specialising in operating on the brain under local anaesthetic, Marsh became the subject of Your Life in Their Hands, a major BBC documentary which won the Royal Television Society Gold Medal. He was also the topic of The English Surgeon which showed his efforts in mentoring junior neurosurgeon Igor Kurilets and other neurosurgeons in the former Soviet Union.
In 2014, Marsh released a captivating best-selling book, Do No Harm: Stories of Life, Death and Brain Surgery, which recollected times when he would look death in the eye whilst making decisions that a neurosurgeon faces on a day-to-day basis. The memoir by no means sugar coats the profession and dives deep into the decision-making processes that take place when patients' lives are balanced on a knife-edge.
Following the success of his first book, Marsh released his second book entitled, Admissions: Life as a Brain Surgeon. This literature is a reflection of the surgeons forty-year career and what the complex role has taught him. He highlights how adopting the mentality that prolonging peoples lives is essential can actually have quite a tragic impact on some patients and their loved ones as well as revisiting some of his endeavours in Nepal and Ukraine. In recognition for his life-saving work, Marsh was appointed the CBE in 2010.
