Daniel Hack Tuke (19 April 1827 – 5 March 1895) was an English physician and expert on mental illness.
His father Samuel Tuke carried on the work of the York Retreat and reported on its methods and its results.
In 1845 Daniel Tuke entered the office of a solicitor at Bradford, but in 1847 began work at the York Retreat.
In 1858, in collaboration with John Charles Bucknill, he published a Manual of Psychological Medicine, which was for many years regarded as a standard work on lunacy.
[3] In 1892 – in cooperation with many others as contributors, including the French neurologist Jean-Martin Charcot – he edited a Dictionary of Psychological Medicine in 2 volumes.
