American zoologist, one of the founders of biometry, the application of statistics to biology and medicine.
...just dealing with mathematical theory, Pearson’s papers most often applied the tools of statistics to scientific problems. With the help of his first assistant, George Udny Yule, Pearson built up a biometric laboratory on the model of the engineering laboratory at University College. As his resources expanded, he was able to recruit a devoted group of female assistants and a succession of...
