Second-Generation Nobel Laureate?

Has there ever been a second-generation Nobel Prize winner (i.e. the son or daughter of a fellow Nobel laureate)? How about (and this sounds likelier) a Nobel laureate who was a student of another one?

Irene Joliot-Curie, daughter of Pierre and Marie Curie, won the 1935 Nobel Prize for Chemistry along with her husband Frederic Joliot-Curie. Of course, she had really good genes.

And many Nobel laureates have studied under prize winners.

The Braggs, father and son won it in 1915. J. J. Thomson won it in 1906 and his son G. P. Thomson won it in 1937.
