The announcement of the gift was made at a press conference in Chicago at the Conrad Hilton Hotel. Dr. Emmerson Ward, chairman of the Board of Governors, Mr. Atherton Bean, chairman of the Board of Trustees, and Mr. Hilton, spoke briefly describing the intent and proposed use of the gift.
The ten million dollars was used for a major laboratory building, named the Conrad N. Hilton Medical Laboratory and Research Center in Human Behavior. This was the first building in the Mayo complex designed specifically for laboratory medicine.
Part of the building was devoted specifically to research in human behavior. Other areas housed laboratory functions for patients and facilities for research in procedures development. Educational and research facilities for hematology, nuclear medicine, clinical chemistry, microbiology, and blood banking were also located in the building, together with regional and reference laboratory programs.
