Pension once consisted of the Inn's Readers. The position of Bencher originated as an expedient, at first rarely used, for co-opting men onto Pension who were deemed necessary but for whatever reason - poor health, excessive external commitment or the like - were unable to serve as Readers. Francis Bacon was an early example, but by no means the first: he was elected a Bencher in 1586 without first serving as a Reader, although he did later do so, in 1588 and again in 1600. Benchers had replaced Readers as the governing body of the Inn by the mid-17th century. Even without the duties of readership, the post was unpopular, and the Pension minutes contain long lists of members who preferred to be fined rather than to serve: in 1727 two had their chambers padlocked by order of Pension in an attempt to force them to accept the call to the Bench.
During the late 18th and the greater part of the 19th century there were so few Benchers that those that there were often had to take two turns at the Treasurership. It was also apparently occasionally necessary to import them from other Inns.
Royal Benchers are also included in the lists, but for convenience of reference their names are repeated here:

HRH Prince Charles, Prince of Wales - 3 Feb 1975
HRH The Duke of Gloucester - 14 Nov 2000
HRH The Duchess of Cornwall - 15 Feb 2012
HRH Grand Duke Jean of Luxembourg was elected an Honorary Bencher in 1988
