Austin O'Malley

Austin O’Malley (1858–1932) was an American physician and writer remembered chiefly for his aphorisms. Trained in medicine, he combined clinical work with a wide-ranging literary output that included essays, historical and biographical studies, and collections of reflections. His name is most often encountered through frequently quoted maxims, many of them drawn from *Keystone Thoughts* and related compilations, where he distilled observations on character, conduct, and everyday life into concise, memorable lines. O’Malley’s sayings have circulated widely in quotation books and popular anthologies, sometimes detached from their original context, sustaining his reputation as a source of pithy counsel.
