About Raymond Pearl

Raymond Pearl was an American biologist, regarded as one of the founders of biogerontology. He spent most of his career at Johns Hopkins University in Baltimore. Pearl was a prolific writer of academic books, papers and articles, as well as a committed populariser and communicator of science. At his death, 841 publications were listed against his name. An early eugenicist, he eventually became an important critic of eugenics. He also advanced the concept of carrying capacity, although he didn't use the term, and was a Malthusian concerned with resource limits. He was a critic of mass consumption. However, when he attended Dartmouth College at 16 years old, he became fascinated by biology and graduated with a B.A. as the youngest in his class. After Raymond Pearl's death Maude became the managing editor of the journal. During this year he discovered biometry, which seemed to offer a solution to the problems he was concerned with in biology, zoology and eugenics.
