In 1879 he was appointed a member of the Royal Dutch Academy of Sciences (KNAW)[1] and was appointed as director of Bogor Botanical Gardens' Lands Plantentuin in Buitenzorg (Bogor) in the year 1880. Treub worked on tropical flora on Java and organized the Botanical Garden as a scientific institution of botany. Under his leadership many crucial researches were successfully completed on plant diseases of economic crops.
He worked for nearly 30 years at the gardens before returning to the Netherlands in 1909 due to his worsening health. Dr. Treub then settled on the village of Saint-Raphael on French Riviera, where he died in 1910.
