One of the garden's nineteenth-century directors was the botanist Dr Richard Moritz Schomburgk, brother to the German naturalist Robert Hermann Schomburgk.
Moritz Richard Schomburgk was commissioned by the Prussian government to map British Guiana's boundaries, accompanied by his brother Robert, who was to collect natural history specimens for the Royal Museum and the Botanical Gardens in Berlin.
His older brother, Sir Robert Hermann Schomburgk (5 June 1804 - 11 March 1865), carried out geographical, ethnological and botanical studies in South America and the West Indies (in which Moritz Richard participated) and also fulfilled diplomatic missions for Great Britain in the Dominican Republic and Thailand.
