I think that, for many centuries, the Ashkenazi environment rewarded establishing a rigid social structure that studies and followed strict rules (preventing assimilation), but selected very strongly for individuals that could step outside the status quo at the right time. I can see how that would lead to Nobel prize winners.
Given the time scale involved, it doesn’t seem like genetic selection could change more than how well you integrate successful memes. Some anecdotes from my own genealogy about relevant selection pressures:
Marriages were usually arranged by parents to get the best possible match. My great, great grandfather was wealthy for the village they were in. When he needed a husband for his daughter, he asked around for the most promising yeshiva student, and gave him a ten year stipend to continue study for marrying her (apparently the standard was more like 2 years).
When Poland got jumped, my grandparents ended up on the Soviet side of the line. My grandmother went back to the Nazi side twice to try to convince her friends and family that they had a better chance of surviving with the Soviets, but they didn’t want to leave the cities to go somewhere unknown. They were all trapped in the Ghetto system, and liquidated within four years.
My grandfather escaped the soviets twice—the first time, he noticed that his transport train was picking up stowaways who would jump off around curves (turned out they were farmers who lived near the tracks but not a station), and he just pretended to be one of them while everyone else stayed on the train to Siberia. The second time he drank all night with the guards, and convinced them that they would never get in trouble for letting him go to find his wife. Shortly after his third capture, Hitler double-crossed Stalin, and all the Poles were released to go fight the Germans. He always said that you need an escape plan for everything in life, and refused to enter any room with only one exit.

He emigrated to Israel in 1948 with a wife, two kids, and no money. He worked as a day laborer, claiming various construction skills to whoever pulled up and asked. One time he claimed he was a plumber in the old country, and spent two days installing an outdoor toilet. He finally saved up enough to buy a small grocery, so that he could run his own business. He walked out back after buying the place to find—the outhouse he had built years before.
He was definitely a badass, but the cancer was pretty far along by the time I knew him and I didn’t speak Hebrew.

Your grandfather sounds like a badass.
