Josiah Wedgwood, perhaps the greatest English potter who ever lived, epitomized the best of his age. He revolutionized the production of ceramics in Georgian Britain by marrying technology with design, manufacturing efficiency and retail flair. But Wedgwood was radical in his mind and politics as well as in his designs. He campaigned for free trade and religious toleration. Most significantly, he created the ceramic 'Emancipation Badge', depicting a slave in chains and inscribed 'Am I Not a Man and a Brother?' that became the symbol of the abolitionist movement. Tristram Hunt's hugely enjoyable new biography, strongly based on Wedgwood's notebooks, letters and the words of his contemporaries, brilliantly captures the energy and originality of Wedgwood and his extraordinary contribution to the transformation of 18th-century Britain.
