Other places tied to Ejnar Hertzsprung in the record

How to read this page

Every line above is a dated fact taken from a source, with the sentence it came from and a link back to it. Nothing is inferred, and a gap in the record is not evidence that someone was elsewhere.

A tag says how the fact is carried by its source: documented a structured, explicitly dated record, attested a sentence that states the person was there, mentioned a sentence that ties the person to the place without stating presence.
