Q:

Who was the first person to touch the moon rocks?

This might be a stupid question, but I can't find and don't know the answer:
Everyone knows that Neil Armstrong and Edwin "Buzz" Aldrin were the first men to land on/ walk on the moon. But were they the first to physically touch the moon? 
I assume dust particles contaminated their suits and the LM and no doubt they inadvertently made contact, but did they actually deliberately skin-to-sample touch (as opposed to through an EVA suit) the moon rock samples? Or were they preserved for analysis on Earth?

A:

First of all, there are many Lunar Meteorites that have been found, but I'm assuming you don't mean those.
The first bits of the Apollo moon rocks to be touched were dust inadvertently touched by the 2 astronauts that landed on the Moon. All of them touched at least some dust samples on the return trip that were contained outside of the container. Some of it might have been deliberate, see the transcripts:

In addition, the workers who helped the astronauts get out of the Apollo capsule are known to have touched at least some dust. One of their jobs was to get dust off their suits by using tape.
The next candidate are the samples that were sent to world leaders from Apollo 11. While there is no record of the dust that was put in to the display being touched, it seems quite likely that it was at some point in time.
I have searched for some kind of a record of a scientist mishandling one of the moon rocks, and I can't find any definitive record of such.
There are 3 rocks that the public may touch with their bare hands. The first of these went on display in 1976.
In addition, there is a few Apollo rocks that have been stole, and likely touched.
