Commercial career

He entered commercial life and, in 1828, went to the United States, where he worked for a time as a clerk in Boston and Philadelphia.^[1] In 1828, he was requested to supervise a transport of Saxon sheep to the American state of Virginia, where he lived for a time. In the same year, he became a partner in a tobacco factory at Richmond. The factory was burned down, and Schomburgk was ruined.^[1] He suffered further setbacks on the Caribbean island of St. Thomas, where he lost all his belongings in a fire. Consequently, he ceased his business activities.

Geographic and exploration career

In 1830, he left for Anegada, one of the Virgin Isles, notorious for its shipwrecks. Although he did not possess the special knowledge that is required for such work,^[1] he surveyed the island at his own expense and sent to the Royal Geographical Society (London) a report which created such an impression that, in 1835, he was entrusted by that body with conducting an expedition of exploration of British Guiana.

He fulfilled his mission (1835–1839) with great success, incidentally discovering the giant Victoria Regia water lily in 1837 and many new species of orchids, one genus of which, Schomburgkia, was named for him.^[1] He also laid to rest the persistent myth of Raleigh's Lake Parime by proposing that the seasonal flooding of the Rupununi savannah had been misidentified as a lake.^[2] In 1841, he returned to Guiana, this time as a British Government official to survey the colony and fix its eastern and western boundaries. The result was the provisional boundary between British Guiana and Venezuela, known as the "Schomburgk Line", and the boundary with the Dutch colony of Surinam.^[3] He also made further geographical and ethnological observations and was joined there by his brother, Moritz Richard.^[1][4] He repeatedly urged fixing the boundary with Brazil, motivated by his encounters with Brazilian enslavement of local Indian tribes, most of which no longer exist. Schomburgk's survey later played a role in the arbitration of the southern boundary between British Guiana and Brazil, with arbitration by the King of Italy in 1904.

On the brothers' return to London in June 1844, Schomburgk presented a report of his journey to the Geographical Society, for which he was knighted by Queen Victoria in 1845,^[1] and continued in other official capacities. In 1846, he was stationed in Barbados, where he gathered information to compile a geographical and statistical description of the island, later to be published as the History of Barbados published in 1848 by Cass as a library series of West Indian studies.

Diplomatic career

In 1848, he was appointed British consul to the Dominican Republic. In 1850, he signed an advantageous commercial treaty for Great Britain and also secured a truce from Soulouque on behalf of the Dominican government. During the following years, he contributed valuable papers about the physical geography of the island to the journal of the Royal Geographical Society.^[1] For example, he became the first recorded person in history to climb Hispaniola's (and the entire Caribbean's) highest mountain, Pico Duarte, in 1851, naming it "Monte Tina" and almost measuring its height correctly at 3,140 metres (10,300 ft).^[5] In 1857, he was promoted to the position of British Consul-General of Siam, where Britain exercised extraterritorial jurisdiction through consular courts over British subjects. In a letter to his cousin William, Schomburgk notes, "In order to get an insight into the English summary police court proceedings, I was, before I left London, obliged to attend police courts there for some time, also to acquaint myself with these proceedings by the study of books.^[6] Based in Bangkok, he also continued his geographical surveys. The letter gives a short account of his visit to the semi-independent kingdom of Chiang Mai in 1859–60,^[7] and thence by elephant across the mountain range to Moulmein on the Bay of Bengal, returning to Bangkok after a trip of 135 days and approximately 1000 English miles.^[6]

Death

He retired from the public service in 1864, hampered by health problems, and died in Schöneberg on 11 March 1865.
