Harding has made major donations to educational and research institutions through his Winton Charitable Foundation. The foundation funded a professorship at the Statistical Laboratory of the University of Cambridge, the
Winton Professorship of the Public Understanding of Risk, aimed at increasing understanding of the mathematics of risk for individuals and organisations. Harding is also the patron of the Harding Center for Risk Literacy at the
Max Planck Institute for Human Development in
Berlin, Harding's foundation, the David and Claudia Harding Foundation, has pledged £20 million to the
University of Cambridge's
Cavendish Laboratory to establish The Winton Programme for the Physics of Sustainability, an advanced research programme to apply theoretical physics to issues of the sustainability of natural resources. The donation to the
Cavendish is the largest since the famous laboratory was established in 1874. In 2011, Winton began a five-year sponsorship of the
Royal Society Prizes for Science Books which was rechristened the Royal Society Winton Prize for Science Books. Harding's foundation has also committed £5m to the
Francis Crick Institute in London for
cancer research. In 2019 Harding donated £100m to
Cambridge University, the largest donation by a British citizen to any university. The funds will go towards supporting the Harding Scholars, a distinguished postgraduate scholarship system for more than 100 PhD students, similar to the
Rhodes Scholarship and the
Gates Cambridge Scholarship. Additional funding will be used to attract students from under-represented groups, allowing Cambridge to recruit the best and brightest students regardless of their social situation. Harding's £100m benefaction was a landmark donation for UK fundraising efforts and closely followed other major donations by leading US entrepreneurs including
Michael Bloomberg,
Stephen Schwarzman, and
Jaffray Woodriff. The
Labour Party suggested it was a consequence of his Conservative Party donations. ==Political activity==
