Clarke Prize Supporters

Members of the Irvine Family at the 2012 Clarke
Prize Award Ceremony.

The Clarke Prize would not be possible without the vision and support of a very special group of people: the Irvine Family of Orange County, California. Through the Joan Irvine Smith and Athalie R. Clarke Foundation, the Irvine Family helped establish NWRI in 1991 and the Clarke Prize in 1994.

The Clarke Prize was named after Mrs. Athalie Richardson Irvine Clarke, a highly respected philanthropist who passed away in 1993. Fondly known as the "First Lady" of Orange County, California, Mrs. Clarke served on the White House preservation committee and participated in many other political activities. She and her daughter, Mrs. Joan Irvine Smith, ran the Irvine Ranch, one of California's most productive crop farms, and served on the board of trustees of the Irvine Company, a privately held real estate investment company with properties all throughout coastal California. Because of her ties to the land, Mrs. Clarke recognized the vital importance of water and strongly promoted better water science and technology.

As supporters of the Clarke Prize, the Foundation not only sponsors the award, but members of the Irvine family are actively involved with the award ceremony and dinner. The family has attended every Clarke Prize since 1994, presenting each winner with the Clarke Medallion and $50,000 check.

We are grateful to the Irvine Family and Joan Irvine Smith and Athalie R. Clarke Foundation for their outstanding support. Thank you for making the Clarke Prize one of the most esteemed water prizes in the world.
