Heinz and Stafford: A tribute to Heinz von Foerster and Stafford Beer Available to Purchase

In June 1996, Stafford Beer and Heinz von Foerster were invited to Colombia to contribute to a number of events, among others to a symposium about second‐order auditing organized by the National Controller's Office of Colombia in Cartagena de Indias. As part of the occasion, they visited Mompox, a colonial town in the delta of the Magdalena river. During that trip, the author met Stafford and from there on she developed a special relationship with him, similar to that she already had with Heinz. The sad death of both great men of cybernetics within a short period of time was the origin of this tribute.
