### Identifying the Key Concept
The question is focused on a historical figure in the field of atomic theory who contributed to our understanding of the atomic structure, specifically the idea that atoms are mostly empty space.

### Analysis of Each Option
1. **Millikan** - Famous for the oil drop experiment, he measured the charge of the electron but did not focus on the structure of the atom.
2. **Einstein** - Known for his theory of relativity and contributions to quantum mechanics but not primarily credited with discoveries about atomic structure.
3. **Bohr** - Developed the Bohr model of the atom, which describes electron orbits but does not explicitly state that atoms are mostly space.
4. **Rutherford** - Conducted the gold foil experiment, leading to the conclusion that atoms have a small, dense nucleus surrounded by mostly empty space.
5. **Dalton** - Proposed the atomic theory but did not describe the structure of the atom as mostly space.

### Conclusion
Based on the analysis, **Rutherford** is the correct answer because his experimental work led to the understanding that the majority of an atom's volume is void, mostly consisting of space surrounding the nucleus.

### Final Answer
**Rutherford**
