Horowitz

 is one of the few non-ghoulified denizens of Vault 34 to have remained alive in spite of the reactor meltdown.

Background
Horowitz was one of five non-ghoulified Vault 34 dwellers to still live in the vault. He and a few others were trapped when someone detonated a bomb in the pool area, and left an SOS in the terminal outside the reactor room of Vault 34. If the player chooses to redirect control to the backup terminal where Horowitz is located, he will free himself and the other Vault 34 survivors, eventually finding their way to the Aerotech Office Park Suite 300, west-southwest of Vault 34.

He is the de facto leader of the small group of survivors. All of them wear Vault 34 jumpsuits. They can be killed without loss of Karma, NCR reputation and without the NCR turning hostile. It is possible that he is descended from the owners of Horowitz Farmstead, but equally possible that the naming is merely a coincidence.

Quests

 * Hard Luck Blues: At the Aerotech Office Park, he will tell you that his group is really glad to be freed from the vault and is excited in learning more about the surface world. They also mentioned that the NCR office running Aerotech Office Park accepted their group and offered them free food and shelter. You have the option of telling them that you were the one who freed them. If you do so they will express their thanks to you.

Appearances
appears in Fallout: New Vegas.

Bugs

 * After the Vault 34 survivors appear in the Aerotech office park (assuming the player chose to save them), speaking to Horowitz will provide a dialogue option for a reward: a "Vault Trinket"; however, no item is added to your inventory if this dialogue option is selected, and there is no indication within the game's code as to what this item was intended to be.


 * Sometimes Horowitz and the rest of the Vault 34 dwellers will not spawn at Aerotech and even if you saved them, attempting to use the command "player.moveto (ref id) may also not work. You will be teleported to the location within Aerotech, (Aerotech Suite 300) but it will be empty. The only way to fix this is to target each NPC with the console, using prid, and activating them each individually.
