"

In an interview in The British Medical Journal in 2015, he was described as having "spent the past 30 years shedding light in places that others believed to be already illuminated. Prescient and provocative, Le Fanu is the goad to keep doctors humble and scientists on the right track." He admitted the worst mistake in his career was to mistake potassium for aminophylline causing his patient to have a cardiac arrest, "though luckily the crash team did not get stuck in the lift or ask too many searching questions.".[5]
