Although an intimate friend of Lord Byron, he was so dangerous (or disreputable) that his Lordship warned Teresa Guiccioli, his last mistress, not to be alone in Medwin's company. Later, Medwin introduced Byron's daughter to her future husband, Lord Lovelace, and so determined the poet's line of descent. Friend of Washington Irving, gentleman of the old school, neglected Boswell of the nineteenth century, Medwin reported the conversations of Byron, Shelley, Trelawny, Hazlitt, Canova the sculptor, and others. His life and adventures light up little-known aspects of the nineteenth-century literary, military, social, and publishing world—in England, India, Italy, France, Switzerland, and Germany. Medwin served as midwife to the words of a dead man—Lord Byron—who returned to laugh and sneer at the living from the Captain's pages. The Conversations of Lord Byron thus became the most controversial book of the day, going through a dozen editions, in six countries, and being translated into French, German, and Italian. It aroused the wrath, indignation, or enthusiastic interest of such individuals as Goethe, Lady Byron, Lady Caroline Lamb, the Countess Teresa Guiccioli, John Cam Hobhouse (later Lord Broughton), Sir Walter Scott, John Murray, and Washington Irving. Medwin, whose long and adventurous life extended from the rise and flowering of the Romantic Period to the mid-Victorian Age (which he regarded as a dreary decline from the great heights of his youth), was an influence of the first magnitude in determining the early public image of Byron and the reputation of Shelley. This often amusing story, as engrossing as a novel, is drawn from all the available accounts, including many important sources never before published. In effect a new contribution to the biographical study of Byron and Shelley, it clarifies Medwin's relations not only with these two poets but also with many other important and interesting figures of the day.
