Immediately upon retiring from business life, Georg Ludwig Rexroth and his wife Annemarie founded the Georg Ludwig Rexroth-Foundation.

They used the proceeds from the sale of their shares in G. L. Rexroth GmbH to set up a foundation fund with the aim of sponsoring their own development projects in the Third World and ensuring the function of social institutions through financial support.

The funds available to the Foundation each year for distribution originate from the revenues of the Foundation's assets, which are supplemented by further donations from the family, the Mannesmann Group, Bosch Rexroth AG and other private donors.

In building up the Foundation, Georg Ludwig Rexroth was ably assisted by the Personnel Director of Mannesmann Rexroth GmbH, Eugen Tatarko, who was a Board Member of the Foundation until his death on June 11, 1986, by his sons Gerd and Bernd and by Irmgard Heider, the Foundation's authorized officer for many years.

The Foundation has its headquarters in Lohr am Main, Germany.
