1868–1950
Best known as an American statistician and writer, this early 20th-century figure helped shape the study of mental health through data, reports, and public-facing books. His work sits at the crossroads of social reform, public health, and the history of psychiatry.

by Horatio M. (Horatio Milo) Pollock
Born in Schoharie County, New York, in 1868, Horatio Milo Pollock began working young and later built a career as a statistician despite very limited formal schooling. Reliable reference sources describe him as an American statistician, and library records show that he wrote and edited books and reports on mental disease, hospital populations, alcoholism, and related social questions.
Pollock is especially associated with statistical work connected to mental hospitals and public welfare in New York. His publications include Mental Disease and Social Welfare, and records from Project Gutenberg, library catalogs, and other archival sources show a body of work focused on psychiatric statistics and institutional care.
Today, he is mainly of interest to readers exploring the history of psychiatry, public health, and social policy. Some of his writing reflects ideas current in his era that are now outdated or troubling, so he is best read as a historical source rather than a modern guide.
