The biography of Hassall is written by Dr Ernest Gray.
What do we know of Hassall? It is this question which Dr Ernest Gray has set out to answer, and in this pleasantly written and well researched biography he shines a torch-light into the Victorian gloom (otherwise barely lit ‘by candlelight’) and reveals Arthur Hill Hassall as not merely a physician to be remembered for his eponymous thymic corpuscles but also a remarkable figure who excelled in many varied spheres
He died in 1894 at the age of 77.
