“…That led to recognition of a new type of cosmic radiation, the CMB (Penzias & Wilson 1965), maybe a fossil from a Hot Big Bang (Dicke et al 1965). The reaction I recall at Princeton was excitement that there actually is something to detect, as Roll & Wilkinson (1966) did a few months later, maybe from the Hot Big Bang, but at least something to be analyzed. The Nobel Prize Committee was right to recognize Penzias & Wilson: They demonstrated that Bell had a problem, and they complained about it until the community responded.…”

The modest science of cosmology I encountered a half century ago has grown into big science. I comment on steps in this development I think I understand because I was there or, in some cases, wish I had been. Wonderful insights-or lucky guesses-and elegant deductions from measurements were accompanied by the usual mix of unlucky guesses and disregard of unwelcome evidence. I say "usual" because I suspect the course of development of any other natural science is similarly erratic. An example in cosmology is Einstein's homogeneous Universe, which was largely accepted as a working hypothesis when there was scant evidence and seriously challenged after we had a reasonable case for homogeneity. Similar mixes of insight and inattention led to the eventual identification of the 3K microwave background, the demonstration that large-scale structure grew by the gravitational instability of the expanding Universe, and the completion of a tight network of cosmological tests. A half century ago, we had little idea what would become of what we were doing in cosmology. We have a better picture now, but I expect there to be more surprises.

“…In addition to the Princeton measurement, Penzias and Wilson [38] and Roll et al [39] havo made measurements averaging the absolute cosmic background along declinations close to the 40th declination which agree with the Princeton measurements, and are summarized in table 2-6. fI The preceding remarks lead to the following picture ( fig. 2-16) of the continuous cosmic radio background.…”

“…Robert Dicke's group in Princeton was attempting exactly this experiment to detect the cooled remnant of the Big Bang-it was very quickly realised that Penzias and Wilson had discovered the signal sought by the Princeton physicists. Within a few months, the Princeton group had measured a background temperature of 3 0 ¦ 0 5 K at a wavelength of 3.2 cm, confirming the black body nature of the background spectrum (Roll & Wilkinson 1966). …”
