Frank L. Schmidt was born on a dairy farm outside Louisville, Kentucky, on April 29, 1944, the oldest of six children to Swiss German parents with a grade-school education. At his first faculty job at Michigan State University, he met John (Jack) Hunter, with whom he began a prolific, impactful collaboration that lasted until Hunter's 2002 death. Together, they invented the methods of psychometric meta-analysis. He believed that the goal of science is to establish universal principles. Schmidt and Hunter's pioneering development of validity generalization (VG) methods showed that statistical artifacts were responsible for study-to-study differences in cognitive ability tests' validities. Schmidt's influential articles included research on selection, bias, utility, job performance, employee engagement, smoking cessation, psychopathology, and corporate social responsibility. But psychometric meta-analysis was his most far-reaching contribution. Schmidt coauthored four widely cited and used books on the technique. Meta-analysis transformed hundreds of fields, where it became the bedrock of scientific knowledge. Schmidt received many prestigious awards for his significant contributions. Schmidt was a paradigm-shifting scientist, a father of modern meta-analytic techniques, and an ardent and intellectually honest researcher of individual differences. He leaves behind a legacy that will continue to shape the future of psychology and management, but also more broadly, science in general. He offered an elegant and quantitative way of knowing. His legacy will live in those whose intellects continue to be shaped by the ideas that he introduced. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
