There's a bit of a misunderstanding in the question. While there have been many scientists involved in the Apollo missions and the study of the moon, no scientist has ever personally visited the moon.

The individuals who have walked on the moon were astronauts, trained specifically for spaceflight and piloting spacecraft.

However, many scientists played crucial roles in the Apollo program and lunar research, including:

* Designing the spacecraft and experiments: Scientists from various fields like engineering, physics, and geology contributed to the technological development of the missions.

* Analyzing data and samples: Once the astronauts returned, scientists meticulously examined the collected lunar rocks, soil, and data to learn about the moon's composition, history, and potential for future exploration.

So, while no scientist has been to the moon themselves, their contributions are essential to our understanding of Earth's celestial neighbor.
