Arthur Hill Hassall

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 (1788–1871), spending his early career in Dublin, where he also studied botany and the seashore.

[4] 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.

[5] 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.

By the marriages of his grandfather's children, Arthur Hill Hassall was connected to the prominent Sanderson, Coppin, and Straker families in the North of England.
