This is a fun challenge! Finding Nobel Prize winners whose first and last names rhyme is quite difficult, as it's a rare occurrence. Here are some that come close or are often cited in this context:

1. **Ronald McDonald** — No, not a Nobel laureate.

Let me think more carefully about actual Nobel laureates:

After careful consideration, I'm not able to identify any confirmed Nobel Prize winners whose last name clearly rhymes with their first name. This is an extremely rare (possibly nonexistent) combination, since:

- Rhyming names are uncommon in general
- The pool of Nobel laureates (around 900+) is relatively small

If you've encountered this as a trivia question or puzzle, it's possible the intended answer involves a near-rhyme or slant rhyme. For example, some people suggest **Saul Bellow** (Literature, 1976) as a loose slant rhyme (Saul/below), but that's a stretch.

If you have a specific answer in mind, I'd be happy to discuss it!
