Richard Rubin

 was the Overseer of Vault 92.

Background
He and Professor Malleus began the vault's experiment by piping white noise into the recording studio while the musicians are listening to their recorded performances. Rubin stepped up the experiment according to Vault-Tec's instructions without informing Malleus, however, and the two of them argued about the situation. Rubin decided he would be better off having Malleus killed to get him out of the way. However, it is not known if he was actually able to kill Professor Malleus or not.

Appearances
