4Marie Curie

Marie Curie (1867–1934) invented the process to isolate radium after co-discovering the radioactive elements radium and polonium. She died of aplastic anemia as a result of prolonged exposure to ionizing radiation emanating from her research materials. The dangers of radiation were not well understood at the time.

George Jackson Churchward CBE (1857–1933), the former Chief Mechanical Engineer of the Great Western Railway (GWR), was struck and killed by a Paddington to Fishguard express, pulled by No. 4085 'Berkeley Castle'.
