[MANHATTAN PROJECT]: WHEELER JOHN A. (1911-2008) American theoretical physicist, best known for popularising the term 'black hole'. During World War II Wheeler worked with the Manhattan Project's Metallurgical Laboratory in Chicago where he helped design nuclear reactors and later, in the early 1950s, helped to design and build the hydrogen bomb. Typed D.S., John A Wheeler, one page, 4to, n.p., 24^th February 1948. Wheeler responds to a researcher's questionnaire entitled World Inquiry, with their manuscript questions at the head of the page, '1. Were your scientific “debut” easy or difficult? 2. Did means of living…..enable you to make yourself known in science? Or did you live solely through your work of laboratory? 3. What work (or what discovery) made yourself more famous? Which do you consider as your masterpiece?'. Wheeler has typed his answers beneath, in full, '1. The most difficult thing about work in science I have found to be the task of picking from all the problems within one's reach those few which are of the greatest importance. 2. My means of living have come always from my work in science and teaching. 3 (a) My work with Niels Bohr on the mechanism of nuclear fission probably has brought my name to the attention of more people than anything else I did. (b) My work with Feynman in Reviews of Modern Physics on Action at a Distance is probably my most original piece of work', adding his signature below. Immediately beneath Wheeler has added a brief T.L.S.¸ John A. Wheeler, n.p., 24^th February 1948, to Mr. Corbiere, in full, 'I trust these answers will be found satisfactory. I shall look forward to the appearance of what promises to be an interesting book'. Some very light, extremely minor age wear, VG
