In London in 1680 —almost two hundred years be-fore the introduction of a modern postal system—WilliamDocwra set up a "Penny Post" for the collection anddelivery of letters within the limits of London City, whichis a model of efficiency even to this day. Docwraestablished letter boxes at designated points throughoutthe city as well as various branch offices. Letters wouldbe collected from the boxes every hour and would bestamped at the branch office the exact time of their col-lection. This post proved so popular and so lucrativethat Docwra became involved with the Duke of Yorkwho claimed royal prerogative for the delivery of mail.In due course Docwra's post was taken over as a govern-ment function. It continued in operation until 1800 whenit became "The Two-penny Post."
