19151964

19151964 is a numeric string that, when read as two four-digit years, denotes a lifespan from 1915 to 1964. In standard typography this is written with a dash as 1915–1964 and is used to indicate the life dates of a person or the duration of a historical period in biographical or archival contexts.

In biographical and archival practice, the form 1915–1964 is commonly appended after a name to indicate birth and death years. The unpunctuated form 19151964 may appear in databases, filenames, or citation keys where punctuation is avoided; however, it is less legible and can be ambiguous without accompanying context such as a name.

If associated with a person, 1915–1964 identifies someone born in 1915 who died in 1964, and it helps distinguish individuals who share a common name. Without a specific name, the string by itself does not identify a particular person. The exact interpretation depends on context, and the unpunctuated form is typically a data-entry convention rather than standard prose.

Historically, the years 1915–1964 encompass significant mid-20th-century events and eras, including the latter part of World War I, the interwar period, World War II, and the early Cold War. As a life span, it reflects a cohort that experienced rapid political, social, and technological change across many regions.
