Hans Eysenck

Hans Eysenck (1916 to 1997) was a German-born British psychologist, born in Berlin, who left Germany in the 1930s because of his opposition to the Nazi party and built his career in England. He took his PhD at University College London in 1940 and is best remembered for his work on intelligence and personality, including the PEN model of personality, and for promoting behavior therapy. At the time of his death he was the most frequently cited living psychologist in peer-reviewed journals. His legacy is contested: his research on IQ scores and race and on personality and disease risk drew controversy, scholars have identified errors and suspected data manipulation, and fourteen papers were retracted in 2020.
