Because of other privileges associated with seniority, the dean is usually allotted some of the most desirable office space, and is generally either chair or ranking minority member of an influential committee.
It is unclear when the position first achieved concrete recognition, though the seniority system and increasing lengths of service emerged in the early 20th century.
When Ed Markey broke Gillett's record for time in the House before moving to the Senate in 2013 he was still decades junior to the sitting dean.
Muhlenberg, Hartley and Thatcher were among the 13 members who attended the initial meeting of the House on March 4, 1789.
In the eighteenth and nineteenth centuries, some state delegations to the House were often not elected until after the term had begun.
