I'll work through this systematically, comparing the 3rd letters of birth and death countries for Nobel Prize winners.

Let me identify some key examples where the 3rd letter of the birth country is lexicographically lower than the 3rd letter of the death country:

**Notable cases:**

1. **Albert Einstein** - Born: Germany (3rd letter: 'r'), Died: United States (3rd letter: 'i')
   - Wait, 'r' > 'i', so this doesn't qualify.

Let me recalculate more carefully:

**Qualifying Nobel Prize winners:**

1. **Enrico Fermi** (Physics, 1938)
   - Born: Italy (3rd letter: 'a')
   - Died: United States (3rd letter: 'i')
   - 'a' < 'i' ✓

2. **Max Born** (Physics, 1954)
   - Born: Germany (3rd letter: 'r')
   - Died: Germany (3rd letter: 'r')
   - Same country, so doesn't qualify

3. **Felix Bloch** (Physics, 1952)
   - Born: Switzerland (3rd letter: 'i')
   - Died: United States (3rd letter: 'i')
   - Same letters, so doesn't qualify

4. **Emilio Segrè** (Physics, 1959)
   - Born: Italy (3rd letter: 'a')
   - Died: United States (3rd letter: 'i')
   - 'a' < 'i' ✓

5. **Salvador Luria** (Physiology/Medicine, 1969)
   - Born: Italy (3rd letter: 'a')
   - Died: United States (3rd letter: 'i')
   - 'a' < 'i' ✓

6. **Franco Modigliani** (Economics, 1985)
   - Born: Italy (3rd letter: 'a')
   - Died: United States (3rd letter: 'i')
   - 'a' < 'i' ✓

**Final List:**
- Enrico Fermi
- Emilio Segrè
- Salvador Luria
- Franco Modigliani

This pattern appears frequently with Italian-born scientists who emigrated to the United States, since "Italy" has 'a' as its 3rd letter while "United States" has 'i' as its 3rd letter.
