"Sergeant Pepper's Lonely Hearts Club Band" reverberated through Burr B yesterday as Nat Sci 5 students bade bon-voyage to George Wald, professor of Biology.

Wald concluded a 35-minute lecture and then announced that he and his family would leave for Stockholm Tuesday evening to accept his Nobel Prize in medicine. He then asked for "six beautiful girls" to help distribute wine and fresh bread "baked by two wonderful Greek ladies" to celebrate the occasion.

Fifteen Cliffies crowded around the beaming professor. The party lasted for twenty minutes, while a panorama of Stockholm flashed on a screen.

Yesterday's party was a good preparation for Wald's stay in Sweden. "One is pretty much the guest of the nation for a week," he said yesterday. The Swedish television network has already prepared a special program on Wald to be broadcast on the night of his arrival.

He will receive his Nobel medal and scroll from the King of Sweden next Sunday. A week of dinners, parties, and dances will follow. "Then, we'll be taking a plane--what's left of us--for Copenhagen," Wald said last night. He will lecture there and visit friends before returning to Cambridge on December 19.

After he finished his preparations for the trip last night, Wald sighed, "Now all I have to do tonight is write a quiz."
