Evelyn Arthur Smythies, CIE (1885 – 1975), was a distinguished forester and philatelist, born of British parents in India. Smythies was an expert on the ecology of Uttarakhand and Nepal. His careful studies of the earliest postage stamps of India, Jammu and Kashmir, Nepal, and Canada produced groundbreaking handbooks on which philatelists rely, even today.
Born in Dehradun on 19 March 1885 to forestry conservator Arthur Smythies and his wife Gertrude (formerly Gertrude Aston), Evelyn Arthur Smythies was educated at Clifton College, and received his degree in geology and a diploma in forestry from Oxford in 1908, then served in the Indian Forest Service from 1908 until 1940, based in Nainital. He was Chief Conservator of the Forest of Nepal from 1940 through 1947.
Smythies' The Forest Wealth of India appeared in 1924. That same year, with C. G. Trevor, he authored Practical Forestry Management.
Smythies and Jim Corbett proposed that an area around Ramnagar, Uttarakhand be made a "National Park" to protect the threatened tigers and other living things. These include the tiger, elephant, chital, sambar, nilgai, gharial, King Cobra, Indian muntjac, wild boar, hedgehog, common musk shrew, flying fox, Indian Pangolin, and nearly 600 species of birds. In 1936, the Hailey National Park came into being as India's first National Park. It was renamed the Ramganga National Park after India's Independence, but later it was renamed the Jim Corbett National Park in today's Uttarakhand.
