Engraving. Sheet size: 145 x 95mm (5¾ x 3¾"). Trimmed to image. Glued to backing sheet.
A portrait of John Harrison (c.1693 - 1776) bust, in profile to the left, wearing short wig curled over side of head. In oval frame. An illustration to the 'European Magazine'. Harrison was an English carpenter and clockmaker. He invented the marine chronometer, a long-sought after device for solving the problem of establishing the East-West position or longitude of a ship at sea, thus revolutionising and extending the possibility of safe long-distance sea travel. The problem was considered so intractable, and following the Scilly naval disaster of 1707 so important, that the British Parliament offered the Longitude prize of £20,000.
