Sir Henry Alexander Wickham (29 May 1846 – 27 September 1928) was a British explorer and bio-thief who single-handedly brought about the collapse of the Amazon rubber boom.[1] He later claimed in publicity that he was responsible for stealing about 70,000 seeds[1] from the rubber-bearing tree, Hevea brasiliensis, in the Santarém area of Brazil in 1876. However, there was technically no law at the time forbidding their export although there was a requirement for export licence (which he obtained under false pretense), and from the embellishments added to his original account it would appear that Wickham was trying to make his actions more exciting than they really were.[2] The Ayapua Boat Museum (Museo Barco Historicos) in Iquitos, Peru calls his actions "the greatest act of piopiracy in the 19th century, and maybe in history", citing that the seeds were never registered as ship's manifest and that the resulting plantations in Asia brought the rubber boom in South America to a grinding halt. The museum also claims that he was specifically paid by the Royal Botanic Gardens, Kew to collect the seeds.[3]

These seeds he accompanied to the Royal Botanic Gardens, Kew, London,[4] from where seedlings were dispatched to British Ceylon (now Sri Lanka), British Malaya (now Peninsular Malaysia) and Singapore, though the latter was not used for rubber), Africa, Batavia in Dutch East Indies (now Jakarta in Indonesia), and other tropical destinations, thus dooming the Amazon rubber boom.

Henry Wickham was born in Hampstead, north London. Wickham's father, a solicitor, died when young Wickham was only four years old.[5][6][7] At age 20 he traveled to Nicaragua, the first of several trips to Latin America and South America.[6] Returning to England, he married Violet Carter in 1871, whose father would publish Wickham's writings.[6] His first book Rough Notes of a Journey Through The Wilderness from Trinidad to Pará, Brazil, by way of the Great Cateracts of the Orinoco, Atabapo, and Rio Negro, was published by W.H.J. Carter in 1872.[6] He would take the entire family to Santarém, Brazil, where his mother, sister Harriette, and the mother-in-law to his brother, John, would all die by 1876.[6] Wickham knighted in the 1920 Birthday Honours "for services in connection with the rubber plantation industry in the Far East."[8]

Rubber plantations in Asia were much more efficient and outproduced Brazil and Peru. This was because the Asian rubber plantations were organized and well suited for production on a commercial scale whereas in Brazil and Peru, the process of latex gathering from forest trees remained a difficult extractive process: rubber tappers worked natural rubber groves in the southern Amazon forest, and rubber tree densities were almost always low, as a consequence of high natural forest diversity. Moreover, experiments in cultivating rubber trees in plantations in the Amazon showed them to be vulnerable to South American rubber tree leaf blight fungus and other diseases and pests - essentially limiting the South American pioneership in rubber production to hunting-gathering rather than agriculture.

In spite of decades of research in selecting highly productive and disease resistant rubber trees, many commercial rubber trees throughout the world are descended from the seeds Wickham took to Joseph Dalton Hooker in London.

In Brazil, Wickham is labeled as a "bio-pirate" for his role in smuggling the rubber seeds that broke the Brazilian monopoly. In 1876, no Brazilian law would have prevented Wickham's collection of the seeds, but he may have misrepresented his cargo as dead botanical material destined for the herbarium in order to obtain an export license in Belém.
