Beadle, sometimes spelled "bedel" is derived from the Latin "bidellus" or "bedellus", rooted in words for "herald." He was originally an official of the Roman Temple. The word Beadle has also been used to describe early policemen and church or parish wardens.

The Livery Companies, as they evolved, needed a point of contact between the Master, Wardens, and Court of Assistants and the Livery in general. They therefore appointed (and paid for) a Beadle, who took care of the Company's meeting place ('Hall'), called the Court members and/or Livery together on behalf of the Master, and enforced any disciplinary measures decided by the Court.

The modern day Beadle is appointed as a officer of the company and his responsibilities vary from ceremonial duties, facilities management also being a Toastmaster at company banquets.
