Billy Arjan Singh

Rajkumari Amrit Kaur was his aunt and his elder brother was Air Vice-Marshal Kunwar Jaswant Singh, PVSM (1915–1963).

However, one day having shot a young leopard in the lights of his vehicle, he dramatically changed his view of hunting, feeling nothing but revulsion for killing and vowing that from then on he would pursue the cause of conservation.

[4] In July 1976, he acquired a hand-reared female tiger cub named Tara from Twycross Zoo in the United Kingdom, and reintroduced her to the wild in the Dudhwa National Park with the permission of India's then Prime Minister Indira Gandhi.

[7] However, samples of two hybrid specimens constituted a too small base to conclusively presume that Tara was the source of the Siberian tiger genes.

[9] In 2004, Arjan Singh received the Getty Award, administered by the World Wildlife Fund, for his innovative contribution to conservation and for creating public awareness.
