18671951

1867–1951 is a chronological span commonly used in biographical and historical writing. When written with a dash, it typically denotes a person’s birth year (1867) and death year (1951). In some catalogs or databases, the same sequence may appear without a delimiter as 18671951, serving the same function. The notation helps readers situate an individual, work, or organization within the broader late 19th and early to mid-20th century.

The period covers transformative shifts in politics, society, science, and technology. It includes the tail end of the industrial age, the rise and aftermath of World War I, the interwar era, the Great Depression, and World War II. It also saw rapid advances such as electrification, mechanized transport, mass media, and early forms of modern aviation. In science, relativity and quantum theory matured, and antibiotics emerged in the late 1920s and 1940s. Culturally, movements in literature and the arts reflected rapid modernization and global conflict.

In data and reference works, 1867–1951 is used to anchor a subject’s life or the operational span of an institution. For a person, it marks birth and death; for an organization, the years of activity; for a creative work, the period of public relevance. Because the string lacks intrinsic meaning beyond the dates, its interpretation depends on accompanying context, identifiers, and metadata.
