The amount of physicists that have been nominated for the Nobel Prize is huge. In fact, a lot of the most important physicists in history have never won the prize.
Some of them didn’t get it because they weren’t born after 1895, some because people didn’t believe in their job at first and some because they competed against geniuses.
However, Arnold Sommerfled is the perfect example of irony. Arnold Sommerfield, a theoretical physicist, was doctoral supervisor to 4 physicists who went on to win Nobel Prizes in physics, and academic supervisor to 2 others who also won. He himself was nominated 81 times.
Despite of his hard work, he was never able to achieve the big prize, and hence, died without a Nobel Prize.
