What is the AIS Foundation?

Incorporated in August 1971 in the State of Missouri, the AIS Foundation was approved in November 1972 as an organization which is not a private foundation, thereby making gifts or bequests tax-deductible on donors' income or estate tax returns. In the belief that a completely informed public will be a supporting public, we present here the questions most frequently arising, with the answers, concerning the Foundation.

The purposes of AISF are to foster, encourage, and sponsor scientific and educational research in the improvement of the genus Iris and the stimulation of widespread interest therein.

Mission Statement

For the reference, research, and education of horticultural, scientific, and general audiences, the AIS Hager/DuBois Memorial Iris Library collects and makes available published literature, archives, and visual records pertaining to the genus Iris.


In 1920 when the American iris Society was being founded by John Wister (its first president) and others, Wister wrote in The Flower Grower about his dream of an Iris Library. He thought it would be a traveling library so that it would be available to everyone. Little did he know that this availability would finally occur with the internet.

That availability now takes the form of the Iris Encyclopedia

Besides this virtual library the AIS Foundation also maintains a physical library where one can find additional literature that is still under copyright and cannot be included online. The AIS Library also contains memorabilia pertinent to the Iris Society. You are invited to visit this real world library by appointment with the AIS librarian. Please consider making contributions of literature and memorabilia to the AIS Library via the AIS Librarian.

Details of the physical library are shown on the AIS Library page
