The term "The Great Depression '' is most frequently attributed to British economist Lionel Robbins, whose 1934 book The Great Depression is credited with formalizing the phrase, though Hoover is widely credited with popularizing the term, informally referring to the downturn as a depression, with such uses as "Economic depression can not be cured by legislative action or executive pronouncement '' (December 1930, Message to Congress), and "I need not recount to you that the world is passing through a great depression '' (1931).
