and to form generalizations. This of course is subject to change when the group gets together." According to Stottler Henke Associates, besides the proposal's authors, attendees at the conference included Ray Solomonoff, Oliver Selfridge, Trenchard More, Arthur Samuel, Herbert A. Simon, and Allen Newell. The actual participants came at different times, mostly for much shorter times. Trenchard More replaced Rochester for three weeks and MacKay and Holland did not attend—but the project was set to begin. Around June 18, 1956, the earliest participants (perhaps only Ray Solomonoff, maybe with Tom Etter) arrived at the Dartmouth campus in Hanover, N.H., to join John McCarthy who already had an apartment there. Ray and Marvin stayed at Professors' apartments, but most would stay at the Hanover Inn. Dates The Dartmouth Workshop is said to have run for six weeks in the summer of 1956. Ray Solomonoff's notes written during the Workshop, however, say it ran for roughly eight weeks, from about June 18 to August 17. Solomonoff's Dartmouth notes start on June 22; June 28 mentions Minsky, June 30 mentions Hanover, N.H., July 1 mentions Tom Etter. On August 17, Ray gave a final talk. Participants Initially, McCarthy lost his list of attendees. Instead, after the workshop, McCarthy sent Ray a preliminary list of participants and visitors plus those interested in the subject. There were 47 people listed. Solomonoff, however, made a complete list in his notes of the summer project: Ray Solomonoff Marvin Minsky John McCarthy Claude Shannon Trenchard More Nat Rochester Oliver Selfridge Julian Bigelow W. Ross Ashby W.S. McCulloch Abraham Robinson Tom Etter John Nash David Sayre Arthur Samuel Kenneth R. Shoulders Shoulders' friend Alex Bernstein Herbert Simon Allen Newell Shannon attended Ray's talk on July 10 and Bigelow gave a talk on August 15. Ray doesn't mention Bernard Widrow, but apparently he visited, along with W.A. Clark and B.G. Farley. Trenchard mentions R. Culver and Ray mentions Bill Shutz. Herb Gelernter didn't attend, but was influenced later by what Rochester learned. Gloria Minsky also commuted there (with their part-beagle dog, Senje, who would start out in the car back seat and end up curled around her like a scarf), and attended some sessions (without Senje). Ray Solomonoff, Marvin Minsky, and John McCarthy were the only three who stayed for the full-time. Trenchard took attendance during two weeks of his three-week visit. From three to about eight people would attend
