Henry Wadsworth Longfellow (1807-82) was an American poet and the author of many works including Hyperion (1839) and The Song of Hiawatha (1855). In 1868 he visited Tennyson on the Isle of Wight. Tennyson took his guest to be photographed by Cameron, commenting: ‘You will have to do whatever she tells you. I will come back soon and see what is left of you’.
