Sir Henry Nicholas Ridley

Sir Henry Nicholas Ridley C.M.G. (1911), M.A. (Oxon), F.R.S., F.L.S., F.R.H.S. (b. 10 December 1855, West Harling Hall, Norfolk, England - d. 24 October 1956, Kew, Surrey, England). A botanist, geologist and the first Scientific Director of the Singapore Botanic Gardens from 1888 to 1911, and the one who spent many years promoting rubber as a commercial product. His research led to his important discovery in 1895, a means of tapping which did not seriously damage the rubber trees. With this advanced method, plantations thrived, and rubber became the most important enterprise in the Straits Settlements. His advocacy for the crop, plus a sharp increase in demand as the auto industry developed, rubber was the key to the twentieth century prosperity of Malaya and Singapore. Malaya was the world's number one rubber producer for many years. In the world encyclopedias, Ridley, Henry Nicholas is known as 'the English botanist who was largely responsible for establishing the rubber industry in the Malay Peninsula'. Ridley is also known as the "father" of the rubber industry, and his invented 'tapping technique' is still being used all around the region where rubber plantations exist. Ridley retired from Singapore in 1911 and spent the rest of his life back in England. He died on 24 October, 1956, just a few months before his 101st birthday. Ridley Park is named after him.

Para rubber-tree seeds (botanic name Hevea brasiliensis) were collected in the Amazon in an 1876 expedition. These were sent to the Royal Kew Gardens, from which three thousand were sent to Ceylon, and from there twenty-two para rubber plants arrived and were grown in our Botanic Gardens in 1877, twelve years before Ridley's arrival in Singapore.

Early life
Ridley was born at West Harling Hall, Norfolk, England, on 10 December 1855. Son of Rev. Oliver Matthew Ridley and Louisa Pole (Stuart), his mother died during his infancy, so he had no memory of her. He had an early and intense interest in the world of nature around him, especially entomology and Coleoptera, and decided while still at school that his life's work would be dedicated to the study of natural history in the tropics.

Ridley was educated at Haileybury School which had no biology classes, but he was an active member of the school's 'natural history society'. At Exeter College, Oxford, he obtained second class honours in Science in 1877, and was also awarded the Burdett-Coutts Geological Scholarship.

Early work
From 1880, Ridley was assistant in the Botanic Department of the British Museum, and received a munificent salary of £100 a year. With this, his first encounter with botany, there was much that was new to him and to learn. He studied a series of collections of specimens sent to the Museum from many parts of the tropics. This gained him a remarkably wide knowledge of tropical plants, especially of Monocotyledons. His reports were published and he also continued to publish papers on zoological subjects. In 1887, sponsored by the Royal Society, he was accompanied by the zoologist G. A. Ramage, and made an expedition to the island of Fernando de Noronha (off the coast of Brazil), and wrote reports on the Botany, Zoology and Geology of the island. He worked with the British Museum until 1888, when at the age of 33, he was selected to fill the directorship of the Botanic Gardens in the Straits Settlements.

Ridley was appointed Director of the Botanic Gardens on 25 September 1888, to take charge of the forests and gardens in the Straits Settlements, especially the Botanic Gardens in Singapore. Here he recognised the agricultural potential of Para rubber trees (Hevea brasiliensis) and conducted experiments that convinced him of the enormous economic potential of rubber as a plantation crop. He began a campaign to establish a rubber industry. He prepared specimens of this cultivated rubber, and exhibited them here in 1890, the first specimens of cultivated rubber ever shown to the public. Most of the early rubber estates in Malaya, beginning about 1896, were planted with Ridley's seeds.

Discoveries and creations
Ridley's research on rubber led to his discovery and development of a practical and improved method of latex gathering, a more efficient method of rubber-tapping, without killing the tree. His more advanced and successful 'tapping technique' encouraged planters to grow rubber, and rubber plantations appeared everywhere. Rubber became the most important enterprise in the Straits Settlements.

The 'Father' of the rubber industry in Malaya.
It was Ridley who recognised the agricultural potential of rubber trees and spent years researching and promoting their use. His nickname "Rubber" and "Mad" Ridley was because of his persistence in persuading Malayan coffee planters to grow rubber trees instead. There were rejections and considerable initial opposition among planters, but Ridley persisted, and by 1896 he succeeded when the first rubber estates were planted using his seeds. From this beginning the rubber industry grew into one of the economic mainstays of the Malay states and the Straits Settlements. His advocacy for the crop, plus a sharp increase in demand as the auto industry developed, made rubber the key to the twentieth century prosperity of Malaya and Singapore. Malaya was the principal producer for many years.

Ridley retired and left Singapore in February 1912, and spent the rest of his exceptionally long life in continued research, writing and living near the Royal Botanic Gardens at Kew, England. Apart from various journeys abroad, he made two trips back to Singapore and Malaya in 1917 and 1922. At the age of eighty-three, he married Lily Eliza Doran, who, with her sister, most devotedly cared for him in his last years. Until he was over ninety years old, he attended the Linnean Society meetings with great regularity. From the autumn of 1953, he was unable to leave his house, but sat at his desk every day and wrote letters and his diary until a severe illness, just before his ninety-eighth birthday, caused an almost complete loss of sight. His gradually increasing deafness made communication with him difficult, but his mind remained clear, and he loved to tell of his varied experiences and early life, especially in Malaya.

Ridley's career of a quarter of a century in Singapore with indefatigable literary contributions to botanical science, were recognised and he was made a Fellow of the Linnean Society in 1881, and, Fellow of the Royal Society (F. R. S.) in 1907; the second 'Malayan' to be elected an F.R.S., one of the greatest honours a scientist can receive. The first was Sir Stamford Raffles. Upon the recommendation of the Straits Settlements Government, he was knighted with the title, C. M. G. (Companion of the Order of St. Michael and St. George), in 1911 before he retired in February 1912. The list of Gold Medals he received include, the Rubber Growers Association Gold Medal in 1914, the Frank N. Meyer Medal of the U.S. Department of Agriculture, in 1928; the Linnean Society of London Gold Medal in 1950, and the Colwyn Medal of the Institution of the Rubber Industry in 1955. His name can be found in the world encyclopedias for his discoveries. He was named "father" of the rubber industry.

As a botanist, Ridley also carried out an extensive study of plants of the Malay Peninsula, especially monocotyledons, and published at least three hundred articles, and educational books, including a five-volume "Flora of the Malay Peninsula" in 1925. He was editor of the Agricultural Bulletin which became the Malayan Agricultural Journal, and an active member and contributor to the Journals of Royal Asiatic Society, Straits Branch. His two most important written works are the five-volume, "Flora of the Malay Peninsula" published in 1925, and "The Dispersal of Plants throughout the World" published in 1930. Books by Henry Ridley at the National Library include:

The Ridley Centenary 1855-1955
Ridley's 100th birthday in 1955 was celebrated quietly at home, and he received congratulations from the Royal Society, the Government of Singapore with a personal visit from the Chief Minister, other official bodies, as well as relatives and old friends. To commemorate the celebrations, a souvenir tribute book, "The Ridley Centenary - Henry N. Ridley 1855-1955" was printed, and from 10-17 December, 1955, the Botanic Gardens held special exhibitions, music entertainment, and was floodlit at night to highlight exhibits.

Sir Henry Nicholas Ridley died on 24 October 1956, almost 101 years of age, at 7 Cumberland Road, Kew, Surrey, England. The funeral service was held at St. Anne's Church in Kew Green. Ridley Park is named after him.
