The S.W. Williston Diptera Research Fund is a Smithsonian Institution administered endowment fund established for the increase and diffusion of knowledge about Diptera.
The endowment was initiated in the 1970s by the late F. Chris Thompson (1944–2021) and has grown to its current size primarily through his contributions.
The S. W. Williston Diptera Research Fund is based at the National Museum of Natural History, Washington DC, U.S.A.
The French National Research Institute for Sustainable Development is an internationally recognised multidisciplinary organisation, working mainly in partnership with countries in the Mediterranean and intertropical zone.
