Donald Eric (D. E.) BroadbentCBE,[1]FRS[2] (Birmingham, 6 May 1926 – 10 April 1993)[3] was an influential experimental psychologist from the United Kingdom.[4] His career and research bridged the gap between the pre-World War II approach of Sir Frederic Bartlett[5] and what became known as cognitive psychology in the late 1960s. A Review of General Psychology survey, published in 2002, ranked Broadbent as the 54th most cited psychologist of the 20th century.[6]
