Daniel Endesha

"Sadie, I know I've been busy, and we don't always have time to talk. But sweetheart... you make me very, very proud."

- Dr. Endesha to Sadie after she makes suggestions to help track the Covenant.

Dr. Endesha was a scientist largely responsible for the management of the Superintendent. He was also Sadie Endesha's father. When Sadie was a child, he programmed Vergil, a subroutine of the Superintendent to take care of her.

During the Covenant attack, he was inside the Superintendent's data center, and observed several Huragok free one of their companions, which started fixing the Superintendent. He was killed when Commissioner Kinsler had the Data Center's fire extinguishing systems activated, flooding the facility with argon.

Trivia

 * His body can be found in Halo 3: ODST by following the lone NMPD officer through the level Data Hive. The officer will eventually turn hostile and you will have to kill him. The final Audio Log can be found on the wall right next to the doctor's body. You can tell which door his office was in. It is most likely the one with the most ice around it.
