Arthur Hill Hassall

From Wikipedia, the free encyclopedia

Arthur Hill Hassall (13 December 1817, Teddington - 9 April 1894, San Remo) was a British physician, chemist and microscopist who is primarily known for his work in public health and food safety.

He entered medicine through apprenticeship in 1834 to his uncle Sir James Murray, spending his early career in Dublin, where he also studied botany and the seashore. In 1846 he published a two-volume study, The Microscopic Anatomy of the Human Body in Health and Disease, the first English textbook on the subject.

After further studying botany at Kew and publishing on botanical topics, particularly freshwater algae, he came to public attention with his 1850 book A microscopical examination of the water supplied to the inhabitants of London and the suburban districts, which became an infuential work in promoting the cause of water reform. In the early 1850s he also studied food adulteration; his reports were published in The Lancet by reformer Thomas Wakley and led directly to the 1860 Food Adulteration Act and subsequent further legislation against the practice.^[1]

He also worked as physician at the Royal Free Hospital, but required long breaks through ill-health due to pulmonary tuberculosis, and in 1869 moved to the Isle of Wight. On the basis of his experience of the microclimate of the Undercliff, he established the National Cottage Hospital for Consumption and Diseases of the Chest (later Royal National Hospital for Diseases of the Chest), a sanatorium at Ventnor, Isle of Wight.

From 1878 onward, aiming to rest in warmer climates, he spent most of his time in Europe, gaining permission to practise both in San Remo, where he and his family lived, and Lucerne, where he worked in the summer. During this time he wrote extensively on climatic treatments for tuberculosis, works such as the 1879 San Remo and the Western Riviera Climatically and Medically Considered. ^[2][3] His autobiography, The narrative of a busy life, was published in 1893.

Two medical terms are named after Hassall: Hassall's corpuscles, which are spherical bodies in the medulla of the thymus gland, and Hassall-Henle bodies, which are abnormal growths in the Descemet membrane of the eye.

His Ventnor hospital operated until 1964 when it closed, made obsolete by drug treatment of tuberculosis, to be demolished in 1969. Its grounds are now the site of Ventnor Botanic Garden.^[4]
