Green Bank conference (1961)





An informal, private gathering convened by the Space Science Board, at Green Bank in November 1961, on the subject of "Intelligent Extraterrestrial Life." Following the publication of Cocconi and Morrison's seminal paper on SETI and Drake's pioneering Project Ozma, the aim was, in the words of the conference organizer J. P. T. Pearman:
... to examine, in the light of present knowledge, the prospects for the existence of other societies in the galaxy with whom communications might be possible; to attempt an estimate of their number; to consider some of the technical problems involved inthe establishment of communication; and to examine ways in which our understanding of the problem might be improved.
In addition to Pearman, the attendees were Dana Atchley, Melvin Calvin, Giuseppe Cocconi, Frank Drake, Su-Shu Huang, John Lilly, Philip Morrison, Bernard Oliver, Carl Sagan, and Otto Struve. The group whimsically constituted itself "The Order of the Dolphin" because of Lilly's work on dolphin communication (see dolphins, as a form of alien intelligence). Subsequently, Calvin had buttons made showing a dolphin emblem from an ancient Greek coin and sent one to each participant. During the conference, Calvin was awarded the Nobel Prize in Chemistry, an event anticipated by Pearman who had smuggled in three celebratory bottles of champagne. Drake presented the now-famous Drake Equation in an effort to formulate mathematically the conference's central problem. During each session, a different factor of the equation was discussed.
