for a renewal of interchange, while Bush defended current policy. Only when he returned to Washington did he discover that Roosevelt had agreed with the British. The Quebec Agreement merged the two atomic bomb projects, creating the Combined Policy Committee with Stimson, Bush and Conant as United States representatives. Bush appeared on the cover of Time magazine on April 3, 1944. He toured the Western Front in October 1944, and spoke to ordnance officers, but no senior commander would meet with him. He was able to meet with Samuel Goudsmit and other members of the Alsos Mission, who assured him that there was no danger from the German project; he conveyed this assessment to Lieutenant General Bedell Smith. In May 1945, Bush became part of the Interim Committee formed to advise the new president, Harry S. Truman, on nuclear weapons. It advised that the atomic bomb should be used against an industrial target in Japan as soon as possible and without warning. Bush was present at the Alamogordo Bombing and Gunnery Range on July 16, 1945, for the Trinity nuclear test, the first detonation of an atomic bomb. Afterwards, he took his hat off to Oppenheimer in tribute. Before the end of the Second World War, Bush and Conant had foreseen and sought to avoid a possible nuclear arms race. Bush proposed international scientific openness and information sharing as a method of self-regulation for the scientific community, to prevent any one political group gaining a scientific advantage. Before nuclear research became public knowledge, Bush used the development of biological weapons as a model for the discussion of similar issues, an "opening wedge". He was less successful in promoting his ideas in peacetime with President Harry Truman, than he had been under wartime conditions with Roosevelt. In "As We May Think", an essay published by the Atlantic Monthly in July 1945, Bush wrote: "This has not been a scientist's war; it has been a war in which all have had a part. The scientists, burying their old professional competition in the demand of a common cause, have shared greatly and learned much. It has been exhilarating to work in effective partnership." Post-war years Memex concept Bush introduced the concept of the memex during the 1930s, which he imagined as a form of memory augmentation involving a microfilm-based "device in which an individual stores all his books, records, and communications, and which
