FIS Foundation

In 2015, FIS received one of the most generous donations ever made to an international school. Drs. Hazel and Rolf-Rudiger Stroth, who were among the small group of individuals who helped to establish FIS in 1961, bequeathed approximately €26 million to the school. Over €6 million was directly applied to facility enhancements and program improvements, and the remainder was placed in a separate non-profit foundation with the sole purpose of creating an endowment to support future FIS initiatives through income derived from the invested principle. 

The funds have been governed by an FIS Foundation Supervisory Board, made up of the FIS Board of Trustees; the investment management is executed by a Foundation Executive Board, a group of current and past FIS parents and administrators appointed by the Supervisory Board, who work with experienced external financial advisors.

Foundation Objectives

The Foundation Board has engaged a professional investment firm, HQ Trust, to directly manage the endowment funds with a strategy to pursue investments that do not involve any undue risks but result in a steady income stream to help create new opportunities for future generations of FIS students. As other generous benefactors add to this endowment in years to come, it will remain a cornerstone of both financial stability and innovation for FIS.

Foundation and Executive Board

The Foundation Executive Board is charged with managing the Foundation with the intent of safeguarding the principal and periodically using income from investments to support the future needs and aspirations of the school. The work of this group is regularly reviewed by the FIS Board of Trustees.

The FIS Foundation was established in March 2016 as a foundation (Stiftung) under German Civil Law (Bürgerliches Recht) possessing legal capacity. It is located in Oberursel, An der Waldlust 15, as a not-for-profit organization.

Initial Disbursement of Funds

In the Fall 2021, the first disbursement of funds is expected to be made available to FIS to support four key initiatives that are of particular importance in the current life of the school and which undoubtedly would have been supported by the Stroth family. They include: Social and Emotional Well Being, Leadership and Global Citizenship, Financial Support for an FIS Education, and Progressive Teaching Practices.

Leaving a Legacy: Hazel and Rolf-RĂ¼diger Stroth

Drs. Hazel and Rolf-Rudiger Stroth were both inspired by and helped to inspire the mission of FIS in its early years. 

It is a great privilege and singular responsibility for the school to be charged by the Stroths’ generosity with carrying on their work for, and devotion to the cause of, international cooperation and understanding.
