About the author
Born in Philadelphia on April 17, 1841, Harrison Allen studied medicine at the University of Pennsylvania and went on to serve as a surgeon in the Union Army during the American Civil War. After the war, he built his career in Philadelphia as a physician and teacher, working at several hospitals and later joining the faculty of the University of Pennsylvania.
Allen is remembered for the unusual range of his interests. Alongside his medical work, he was an anatomist and zoologist whose research explored the structure of mammals, with notable attention to bats and primates. That mix of careful clinical observation and curiosity about the natural world gave his writing a broad reach for its time.
He died in Philadelphia on November 14, 1897. Today, he stands out as one of those 19th-century scholars who did not stay inside a single field, but helped connect medicine and natural history in the same life.
