==Biography==
===Early life===
Aaron Siegel was born in 1866 in Essex County, New Jersey. He eventually became a physicist studying at Cornell University. Siegel was extremely intelligent, becoming a highly renowned scientist at his place of study.
===Discovery of the anomalous===
Siegel joined several organizations involving the occult, eventually meeting the Gate Guardian in Iraq. Contrary to other commands from the angel, the Guardian told him to "PROTECT".Entry Page: 001 - Dr. Clef's Proposal Siegel disappeared from public record after 1891, possibly founding the SCP Foundation.
He sired a child, who would later become known as Dr. Charles Gears. Siegel also discovered a way to expand his lifespan, which allowed him to live well past the average human lifespan. It's possible that he is a shape-shifter, as well; he was spotted as an old man in the company of O5-2 and as a young teenager from security bunker footage.
==Alternate realities==
=== Dr. Mann's Proposal===
One day, while at his family home in Essex County, he discovered a gravel path that went far longer than it should have, before inexplicably returning him to where he started. Siegel built a shack nearby where he devised many experiments, one of which produced SCP-005. 
Several others joined Siegel, including his brother, Thomas Carter, and fiancée Agnes Peterson, creating the SCP Foundation. They all created various anomalous items, including SCP-006, SCP-018, SCP-011. They eventually moved on to lifeforms, creating SCP-014 and SCP-007. Siegel also accidentally made SCP-033 during an experiment in his laboratory. He eventually disappeared over time as the early Foundation created more and more terrible creatures.Entry Page: 001 - Dr. Mann's Proposal
=== Ecce Perago===
In this reality, O5-1 converted himself into a mechanical being, buried deep underground. During Everett Mann's assassination of the entire O5 Council, he discovered O5-1's location and shut his systems down before pouring liquid concrete into the vents. He accepted this, dying as he should have done a long time ago.Ecce Perago
After his death, a message was sent to his son, Charles Gears, who took his mantle as O5-1.Annon
