Season of birth of schizophrenics was investigated by comparing 915 carefully selected schizophrenic patients with controls matched for age and sex. While the winter‐spring excess of schizophrenic births was similar to Northern Hemisphere findings, further examination of date revealed a new feature: a striking excess of male schizophrenic births for the decade 1915–24. The hypothesis of differential resistance to infection is discussed as an explanation for these findings.
