Two lives. One changing world.

Historical overlap is estimated from birth years; an event in someone’s birth year may have occurred before their actual birthday. Historical overlap means an event occurred during the same calendar year or later; it does not establish awareness, memory, location, or direct participation. Ages are the ages turned during the event year. Events are an illustrative curated selection, not a comprehensive historical record. This is an expanded illustrative selection, not an exhaustive or fully source-audited historical database. Event-level citations are planned for a later release.
