Sheldon Glueck (August 15, 1896 – March 10, 1980) was a Polish-American criminologist. He and his wife Eleanor Glueck collaborated extensively on research related to juvenile delinquency and developed the "Social Prediction Tables" model for predicting the likelihood of delinquent behavior in youth. They were the first criminologists to perform studies of chronic juvenile offenders and among the first to examine the effects of psychopathy among the more serious delinquents. Source: Wikipedia (en)
