Karl Pearson (1857-1936) was an English mathematician and statistician who made significant contributions to the fields of statistics, biometrics, and eugenics. He developed many statistical techniques that are widely used today, including the correlation coefficient and the method of moments. Pearson was a strong advocate of eugenics, which he defined as the science of improving the genetic quality of the human population through selective breeding. He believed that eugenics was necessary to improve the physical and mental health of the population, and he supported policies such as sterilization and immigration restrictions based on eugenic principles. However, his views on eugenics have been criticized for their racist and classist implications. Despite his controversial beliefs, Pearson's contributions to statistics and biometrics have had a lasting impact on the field.
