The Wyss Foundation is a private foundation established in 1998 by Swiss billionaire and former Synthes CEO Hansjorg Wyss, an environmentalist activist. The private foundation, based in Washington, D.C., states that it is “dedicated to supporting innovative, lasting solutions that improve lives, empower communities, and strengthen connections to the land.”[1] In the foundation’s 2013 tax forms, its assets are listed at over $2.1 billion, with $19 million in grants awarded that year.[2]

History and Mission

In 1998, Hansjorg Wyss established the Wyss Foundation to help ensure land conservation in the American West. The foundation states that its mission is “to [support] innovative, lasting solutions that improve lives, empower communities, and strengthen connections to the land.”[3] The foundation highlights a lifetime total of $175 million grants have been awarded to “help local communities, land trusts, and non-profit partners conserve nearly 14 million acres in the West for future generations.”[4]

In 2013, Hansjorg Wyss’ second foundation, the HJW Foundation, was dissolved and merged into the Wyss Foundation, transferring over $283 million in assets.[5]


The Wyss Foundation categorizes its philanthropic investments in three areas: Land, Communities, and Discovery. In the foundation’s 2013 tax returns, over $19 million in grants were awarded.

In 2016, the Wyss Foundation’s more notable gifts included three grants, totaling over $1 million, in support of civic participation; grants were in support of projects aimed at helping local and state governments provide voter registration services and studying why people choose not to vote.[6]
