FounderFounder of The Leprosy Mission Trust India
Wellesley Cosby Bailey is the founder of The Leprosy Mission Trust India (1874)[1], an Indian non-profit working on healthcare, disability and livelihood from New Delhi.
Wellesley Cosby Bailey (1846 - 1937) was an Irish missionary who founded the organisation that became The Leprosy Mission. He died in 1937 at the age of 91.
The Leprosy Mission Trust India dates its founding to 1874, when it was established as the Mission to Lepers by Bailey. It is now the largest leprosy-focused non-governmental organisation in India, working with people affected by leprosy and other neglected tropical diseases, people with disabilities and marginalised communities.
Early life and education
Bailey was born in Ireland in 1846 and was educated, with his three brothers, at Kilkenny College.
Career
Bailey travelled to India in 1869, going to the north of the country, where he encountered people affected by leprosy at a time when there was no cure for the disease and those affected were widely treated as outcasts. In 1870 he married Alice Grahame at Bombay Cathedral.
The mission he began grew into an organised society, of which he became secretary and treasurer while continuing to work from India. He returned to India in 1875 as a lay missionary with the Church of Scotland. In 1886 he was appointed full-time secretary of the Mission to Lepers, and in 1905 became its superintendent.
In 1913 he undertook a final tour of the mission's work in a number of countries, and he retired in 1917 at the age of 71. By then the mission was working in twelve countries and supporting more than 14,000 people affected by leprosy.
In India, the organisation he founded is now The Leprosy Mission Trust India, headquartered in New Delhi and registered as a society. It runs sixteen hospitals, six vocational training centres, four residential care homes for elderly people affected by leprosy, nine community empowerment projects and a molecular research laboratory across nine Indian states. It marked its 140th anniversary in 2014.
