18661936

1866–1936 is a biographical notation used to indicate that a person was born in 1866 and died in 1936. The two years are separated by an en dash, a standard convention in English for representing a range.

In most contexts, the format appears after a person’s name, as in "Jane Doe (1866–1936)." It helps readers quickly locate the individual in time and understand the historical context of their life and work.

The same dates can apply to more than one person, so the dates alone do not identify a unique individual. Additional information such as the person’s full name, occupation, nationality, or notable achievements is necessary to disambiguate.

The interval 1866–1936 covers a period that begins in the late 19th century and ends in the interwar era. It encompasses broad social, technological, and political transformations, including industrial growth, advances in science, and major global conflicts.
