Melvyn Bragg and guests discuss the highly influential American poet Walt Whitman. In 1855 Whitman was working as a printer, journalist and property developer when he published his first collection of poetry. It began: I celebrate myself, And what I assume you shall assume For every atom belonging to me as good belongs to you. The book was called Leaves of Grass. In it, Whitman set out to break away from European literary forms and traditions. Using long lines written in free verse, he developed a poetry meant to express a distinctively American outlook. Leaves of Grass is full of verse that celebrates both the sovereign individual, and the deep fellowship between individuals. Its optimism about the American experience was challenged by the Civil War and its aftermath, but Whitman emerged as a celebrity and a key figure in the development of American culture.

Melvyn Bragg and guests discuss the life, ideas and legacy of the pioneering Swedish botanist Carl Linnaeus (1707 – 1778). The philosopher Jean-Jacques Rousseau once wrote: "Tell him I know no greater man on earth". The son of a parson, Linnaeus grew up in an impoverished part of Sweden but managed to gain a place at university. He went on to transform biology by making two major innovations. He devised a simpler method of naming species and he developed a new system for classifying plants and animals, a system that became known as the Linnaean hierarchy. He was also one of the first people to grow a banana in Europe. With Staffan Muller-Wille University Lecturer in History of Life, Human and Earth Sciences at the University of Cambridge Stella Sandford Professor of Modern European Philosophy at Kingston University, London and Steve Jones Senior Research Fellow in Genetics at University College, London Producer Luke Mulhall

Melvyn Bragg and guests discuss the brutal events of 26 August 1346, when the armies of France and England met in a funnel-shaped valley outside the town of Crécy in northern France. Although the French, led by Philip VI, massively outnumbered the English, under the command of Edward III, the English won the battle, and French casualties were huge. The English victory is often attributed to the success of their longbowmen against the heavy cavalry of the French. The Battle of Crécy was the result of years of simmering tension between Edward III and Philip VI, and it led to decades of further conflict between England and France, a conflict that came to be known as the Hundred Years War.

Melvyn Bragg and guests discuss the Danish prince who became a very effective King of England in 1016. Cnut inherited a kingdom in a sorry state. The north and east coast had been harried by Viking raiders, and his predecessor King Æthelred II had struggled to maintain order amongst the Anglo-Saxon nobility too. Cnut proved to be skilful ruler. Not only did he bring stability and order to the kingdom, he exported the Anglo-Saxon style of centralised government to Denmark. Under Cnut, England became the cosmopolitan centre of a multi-national North Atlantic Empire, and a major player in European politics.

Melvyn Bragg and guests discuss Virginia Woolf's highly influential essay on women and literature, which considers both literary history and future opportunity. In 1928 Woolf gave two lectures at Cambridge University about women and fiction. In front of an audience at Newnham College, she delivered the following words: “All I could do was offer you an opinion upon one minor point - a woman must have money and a room of her own if she is to write fiction; and that, as you will see, leaves the great problem of the true nature of woman and the true nature of fiction unsolved”. These lectures formed the basis of a book she published the following year, and Woolf chose A Room Of One’s Own for its title. It is a text that set the scene for the study of women’s writing for the rest of the 20th century. Arguably, it initiated the discipline of women’s history too.
