Our Beadle is Tony Parker.
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 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.
He would be issued with a Staff of Office, often wrongly called a mace, with which to protect the Master and enforce discipline. The Staff is usually a tall one so that it could be used as a rallying point at Common Hall etc. when the Livery was summoned to "Attend upon the Master".
Tony Parker was a founding member of the Beadles' Guild. The Guild was formed in 1992 with the aim of uniting all Livery Company Beadles for social events, to preserve the traditions of the City of London and the Livery Companies and to assist or advise newly-appointed Beadles in matters of protocol.
