Who did that

Who held the office

Every official who has a page on the ledger: 19 people in 4 offices, newest first. Each page lists the rates that last moved while they held the office.

Dated in office is not authorship: a rate can carry the date of an official who vetoed it or opposed it. The count is rate changes dated in each term; some terms have none on the ledger.
