The story

Founded by Henry Solomon Wellcome in 1936.1

The trust was established to administer the fortune of the American-born British 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 £14 billion 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.

Seeding Drug Discovery Initiative

Also known as SDDI, this five-year initiative started in October 2005 with the remit "to facilitate the development of drug-like small molecules that address unmet medical needs." SDDI was based in London and managed by Richard Davis. Through early 2010, SDDI had provided more than £80 million across 30 projects split between academic institutions and companies. To early 2010, all but one of the company recipients were either start-ups or spin-outs. In May 2010, an additional £110 million was added to the SDDI fund with the intent to extend the initiative for an additional five years.

Supporting global research and development in COVID-19

The Wellcome Trust announced the need for at least $8 billion of new funding for research, development, and supply of treatments related to COVID-19. Wellcome Trust collaborated with the Bill & Melinda Gates Foundation and Mastercard to fund the COVID-19 Therapeutics Accelerator, launching in March 2020 with an initial $125 million in backing.

Improving research culture

In September 2019, Wellcome launched an initiative to reimagine research and improve the culture in which research is conducted. Current incentive structures and, as a result, culture and practices, prioritise publication outputs above all else. This is damaging people's wellbeing and undermining the quality of research itself.

Membership in the Global Health Innovative Technology Fund (GHIT)

In the summer of 2015, the Wellcome Trust joined the Japanese government, 7 Japanese pharmaceutical and diagnostics companies, The Bill and Melinda Gates Foundation, and the United Nations Development Program as funding partner of the Global Health Innovative Technology Fund (GHIT), which funds scientific research and development for anti-infectives and diagnostics for diseases that primarily affect the developing world.
