Dr. Iceberg is a researcher. Not much is known about the origin and past of Ellis "Iceberg" Gill. He originally specialized in the American military and later on was recruited by the SCP Foundation as a researcher. He began working in some sites, most prominently in Site-19 where after some time he was promoted to assistant of the famous Dr. Gears, following his last assistant's exposure to SCP-008. Iceberg found this job difficult and stressing, especially due to being near SCPs like SCP-076-2.
