Deep in the Amazonian rainforest grew a solitary tree. From its bark flowed a milky white sap that changed the world: rubber. It was Sir Henry Alexander Wickham (1846-1928) who was commissioned by the Royal Botanic Gardens in Kew to smuggle seeds from the rubber-bearing tree out of Brazil and bring them to London. From Kew Gardens seedlings were dispatched to Ceylon (Sri Lanka), and Malaya (Malaysia) thus bringing an end to the Brazilian monopoly on rubber production. During this lecture author and explorer Redmond O’Hanlon will talk about the treacherous journey Henry Wickham undertook to obtain rubber seeds of the Hevea brasiliensis.
