John Forbes Royle

John Forbes Royle (10 May 1798 – 2 January 1858), British botanist and teacher of materia medica (pharmacology), was born in Kanpur (then Cawnpore) in India in 1798. He was in charge of the botanical garden at Saharanpur and played a role in the development of economic botany in India.

Early life John Forbes Royle was the only son of William Henry Royle and Isabella Forbes. While still a child, his father died and Royle studied under Sangster of Haddington before going to study at Edinburgh high school. He was influenced by Anthony Todd Thomson to take an interest in botany and natural history. This led him to give up a military career at Addiscombe and to choose to study medicine. He joined the service of the East India Company as assistant surgeon and went to Calcutta in 1819. He served with the Bengal army (at various times with the 17th and 87th Regiments, Native Artillery, Cavalry and Infantry) at Dum Dum and in parts of the North-Western Provinces, where he found time to study botany and geology, and made large collections from the Himalayas. He is responsible for introducing Impatiens glandulifera to Britain.

Saharanpur In 1823 Royle was appointed as the second Superintendent of the botanical garden at Saharanpur which had been established by George Govan of the East India Company in 1816 with the aim of growing medicinal plants and the introduction of new crops of commercial value. Royle was assisted by Hugh Falconer who also took an interest in paleontology. One of Royle's major interests was in the traditional botanical remedies used by Hindu medical practitioners based on which he would later write On the Antiquity of Hindu Medicine (1837). He noted the effectiveness of many of these remedies. He also began a scheme of recording weather data at Saharanpur. He retired from service in 1831 and returned to England but continued to publish several books. In 1851 he superintended the Indian department of the Great Exhibition. In 1852, his recommendation for the introduction of cinchona was approved by the Lord Dalhousie, governor-general of India. Royle produced a report on this in 1853 but work began only in 1860, two years after Royle's death at Acton near London on 2 January 1858.

Botanical works The work on which Royle's reputation chiefly rests is the Illustrations of the Botany and other branches of Natural History of the Himalayan Mountains, and of the Flora of Cashmere, in 2 vols. begun in 1839. In addition he took a special interest in fibre yielding crops such as cotton in his On the Culture and Commerce of Cotton in India and Elsewhere (1851) and The Fibrous Plants of India fitted for Cordage (1855), together with papers in scientific journals.
