David Landon obituary

My father, David Landon, who has died aged 88, was a pioneer in the use of high-resolution electron microscopes to improve the understanding of neuromuscular diseases such as multiple sclerosis, and established a state-of-the-art electron microscopy facility that provided diagnostic services for several London hospitals that ran from the mid-1970s onwards.

Specialising in exploring the microscopic structure and function of nerves and muscles, his early published papers describing structures involved in nerve conduction called the nodes of Ranvier were the start of a fruitful research career that used electron microscopes in diagnostic services for neuromuscular conditions.
