Career-path arc — direction of travel between consecutive home cities. Click for years.

A person's location in a given year is inferred from the origin of their letters (when sending) and the destination (when receiving). Undated letters can't be placed in time and are excluded. Career arcs connect the *primary* (most-active) city in each year, so within-year side trips don't appear on the path itself.
