To win a Nobel Prize is the ultimate accolade for a scientist. However the Nobel prizes have rules which sometimes lead to people being overlooked for a prize: prizes may only be awarded to those still alive at the time of awarding and no more than three people can share any one prize. This has led to some scientists, who many feel have contributed significantly to their field, never receiving a Nobel Prize. Of course this list is highly subjective but I hope I can make good cases that the following were all deserving of a Nobel Prize.
