Alexander was a lifelong, dedicated and gifted birdwatcher, keenly involved in the 20th-century movements for the protection and observation of birds. He and two of his older brothers, Wilfred and Christopher, he took a keen interest in nature. Growing up in a Quaker home devoid of any other forms of entertainment, his interest in birds began at the age of eight, when his older brother Gilbert gave him a book on natural history. In his autobiography he traced the beginnings of this interest in birds to 8.45 am on 25 March 1897, when an uncle pointed out a singing chiffchaff in their garden. It was not until he was 20 that he obtained his first pair of binoculars. He was one of a small group of amateur birdwatchers who developed skills and set new standards for combining the pleasures of birdwatching with the satisfaction of contributing to ornithological science. He made many significant observations, mainly in Britain, but also in India and the United States. Alexander spent most of his time in India and became interested in its birds in 1927. Ornithology at that time was not popular among Indians in India, and when Horace informed Gandhi of an expedition, Gandhi commented, "That is a good hobby, provided you don't shoot them." Horace demonstrated the use of binoculars as an acceptable alternative to the gun and carried them at most times. Horace Alexander joined Sidney Dillon Ripley on an expedition to the Naga Hills in 1950. Ripley named a subspecies of the aberrant bush warbler after Alexander, although this is no longer recognised. In the same year he founded the Delhi Birdwatching Society, along with Lt. Gen. Harold Williams. One of the early members of the organisation was the young Indira Gandhi, and the group encouraged Indian ornithologists such as Usha Ganguli. Many of his notes were mislaid when one of his suitcases was lost in India in 1946. Through his influence on Jawaharlal Nehru, he was instrumental in the designation of the Sultanpur Bird Sanctuary near Delhi. Alexander was also a founder member, in 1929, of the West Midland Bird Club, and its president, during his long residence in Birmingham, England.
Gandhi
Alexander's father-in-law, John William Graham, believed that Gandhi was a subversive and that the Indians were unprepared for self-government. At the Quaker yearly meeting in 1930 the Nobel prize-winning poet Rabindranath Tagore attacked colonial rule in India. The Quakers were disturbed by the address and John Graham was particularly outraged. Afterwards it was agreed that a representative would be sent to India to attempt a reconciliation between the Viceroy, Lord Irwin, and Gandhi. This task was assigned to Horace Alexander, who first met Gandhi in March 1928. He made it possible for Gandhi to attend the 1931 round-table conference in London. After the conference he founded the India Conciliation Group along with Agatha Harrison and Carl Heath. Becoming a close friend of Gandhi, he wrote extensively about Gandhi's philosophy. In 1947 he attempted to intervene to control the violence between Muslims and Hindus and was beside Gandhi in Calcutta on 15 August 1947. He was consulted by Richard Attenborough in the making of the film Gandhi. However, he felt that the scripts did not do justice to the people around Gandhi. In 1984 he was awarded the Padma Bhushan medal, the highest honour given to a non-Indian civilian.
