William Halse Rivers Rivers, FRCP, FRS, (1864-1922) was an English
anthropologist, neurologist, ethnologist and psychiatrist, best known
for his work with soldiers during World War I who were suffering from
shell shock. Rivers's most famous patient was the poet Siegfried
Sassoon. He is also famous for his participation in the Torres Straits
expedition of 1898, and his consequent seminal work on the subject of
kinship. Conflict and Dreams was posthumously published in 1923 a year
after Rivers's death and continues his theoretical reflection on his War
experience as a therapist from his 1920 work 'Instinct and the
Unconscious'.
