Dr. Benjamin Kondraki was an SCP Foundation researcher and former Director of Site-17. Kondraki was a controversial person and did not care much about the consequences of his dramatic antics, which is why he gained many rivals, the most famous of which was Alto Clef.
Following the disorderly killing of SCP-083-D, which involved several other SCPs and caused extreme damage to Site-19, Kondraki was presumably killed for endangering the lives of staff and other contained SCPs.
