Executive summary: Biogerontology

Statistician and biologist Raymond Pearl conducted extensive research into nutrition, death, and eugenics, and he is considered a founding father of biogerontology (the biology-based study of aging). One of America's best-known scientists in the first half of the 20th century, he conducted landmark studies of the heredity and reproduction of poultry, cattle, and people, and founded Quarterly Review of Biology in 1926.

In 1927 he became the first prominent biologist to criticize the eugenics movement, and in 1938 he published a study conclusively linking use of tobacco to increased likelihood of early death. At the height of prohibition in America, he published research showing that the rate of alcohol-related deaths had more than tripled, and another study showing that moderate consumption of alcohol actually extends lifespan. Another Pearl study showed that factors such as relative prosperity and overcrowding decrease birth rates, while poverty and difficult conditions have the opposite effect, increasing birth rates.

Along with Alfred A. Knopf, Pearl was a regular member of H. L. Mencken's "Saturday Night Club", an informal gathering of intellectuals for social, drinking, and musical purposes. He was an outspoken anti-Semite, and supported eugenics for many years before his change of heart. In his 1939 book The Natural History of Population, he used statistical analysis to plot the past and future of world population, and predicted that by the year 2100 world population might reach 2.6 billion.
