The Wellcome Trust was established in 1936 as an independent charity funding research to improve human and animal health. It has an endowment of around £14.5 billion  Now in its 76th year, the aim of the Trust is to "achieve extraordinary improvements in health by supporting the brightest minds", and in addition to funding biomedical research it supports the public understanding of science.
The Trust has been described by the Financial Times as the United Kingdom's largest provider of non governmental funding for scientific research and one of the largest providers in the world. In the field of medical research, it is the world's second largest private funder after Bill & Melinda Gates Foundation.
The Trust was established to administer the fortune of the American-born pharmaceutical magnate Sir Henry Wellcome. Its income was derived from what was originally called Burroughs Wellcome, later renamed in the UK as the Wellcome Foundation Ltd. In 1986, the trust sold 25% of Wellcome plc stock to the public. Overseen by incoming Director of Finance Ian Macgregor, this marked the beginning of a period of financial growth that saw the Trust's value increase by almost £14bn in 14 years, as their interests moved beyond the bounds of the pharmaceutical industry. In 1995, the trust divested itself of any interest in pharmaceuticals by selling all remaining stock to Glaxo plc, the company's historic British rival, creating GlaxoWellcome plc. In 2000, the Wellcome name disappeared from the drug business altogether when GlaxoWellcome merged with SmithKline Beecham, to form GlaxoSmithKline plc.
Support for Open Access 
The Wellcome Trust plays an important role in encouraging publication of research in open access repositories such as UK PubMed Central (UKPMC). The Wellcome Trust believes that maximising the distribution of these papers - by providing free, online access - is the most effective way of ensuring that the research can be accessed, read and built upon. In turn, this will foster a richer research culture.
Public engagement and the Wellcome Collection 
In June 2007 the Wellcome Building reopened after refurbishment as a public venue, housing the Wellcome Collection, the Wellcome Trust Centre for the History of Medicine at University College London and the Wellcome Library. The aim of the Wellcome Collection is to enhance public understanding of medical science and history. The building contains gallery spaces, conference facilities, space for debates, drama and workshops, a café and a bookshop. The galleries show a small sample of works from Sir Henry Wellcome's collection, and host a programme of events and exhibitions. The Wellcome Collection and exhibitions are open to the public free of charge six days a week.
The Wellcome Collection and Wellcome Library are members of The London Museums of Health & Medicine.
The Wellcome Trust's operations are run from two buildings on Euston Road in London. The Wellcome Building, at 183 Euston Road, built in 1932 in Portland stone houses the Wellcome Collection and the adjoining glass and steel building at 215 Euston Road is the Gibbs Building, by Hopkins Architects, which opened in 2004 as the administrative headquarters of the Wellcome Trust.
