# Who discovered the relation between CMB fluctuations and large-scale structure formation?

I haven't been able to find a reference to the first who showed that the small density fluctuations in the cosmic microwave background led to the formation of large scale structure as we know it.

• I don't know too much about the details, but the initial studies of CMB indicated that it was remarkably uniform. That uniformity was strong evidence for the expanding universe model and it dismissed a few other hypothetical models. After observing the uniformity, the next logical step was to look more closely for any slight fluctuations. Not sure if that helps. May 29 '18 at 8:00
