> Einstien won his Nobel for work on the photoelectric effect, not relativity, though obviously the latter mattered more.
The photoelectric effect led to quantum mechanics and the associated science and technology. I don't think it's obvious that relativity mattered more. If you judge by day-to-day use, one could plausibly argue that our understanding of quantum mechanics has a bigger impact.
My high school science teacher told us that he was given the prize for the photoelectric effect because that was a well understood mechanism by the time of the awarding. It was generally understood that relativity was going to be a bigger deal (concept wise), but since it was still so hotly debated / not yet thoroughly accepted, the commission wanted to ensure that he was given a prize before death (the award is not given post-humorously for some reason) and given for something that wouldn't be later rejected.
"In 1905 Albert Einstein published a paper that explained experimental data from the photoelectric effect as being the result of light energy being carried in discrete quantized packets. This discovery led to the quantum revolution."
