William Askham

William Askham was Lord Mayor of London in 1403–1404.

Career
Askham was an apprentice of the famous City of London fishmonger and Lord Mayor Sir William Walworth. He prospered in his trade and eventually followed in his master's footsteps as Sheriff of London in 1398 and Lord Mayor in 1403.

Coat of arms
Askham's arms were blazoned: Gules, a fesse or between three dolphins embowed argent. This design clearly reflected the arms of the ancient Guild of Fishmongers, similar to those of the present Worshipful Company of Fishmongers (see that article).
