The modern SCP phenomenon does not have a single official “creator” in the traditional sense; it grew out of anonymous internet horror writing and then a collaborative community.

Origins of SCP

  • The SCP Foundation started on 4chan’s /x/ (paranormal) board in June 2007, when an anonymous user posted the first SCP entry, SCP-173, as a creepypasta-style document.
  • That first author was later identified as Wesley “Moto42” Williams, who wrote SCP-173 and effectively kicked off what became the SCP universe.

“Who created SCP?” in two senses

When people ask “who created SCP,” they usually mean two slightly different things:

  1. Who started the SCP Foundation concept online?
    • Wesley “Moto42” Williams is credited with the first SCP article, SCP‑173, which set the tone, format, and basic idea of the Foundation securing and containing anomalies.
 * After that, many other anonymous and named writers on the SCP Wiki expanded the universe, so the setting quickly became a huge collaborative project rather than the work of one person.
  1. Who founded the SCP Foundation in the lore?
    • In-universe, different stories give different answers: some mention figures like James Aaron Siegel as a founder in the 1800s, while others describe more mysterious origins such as ancient or multi-organization beginnings.
 * The SCP canon is intentionally fragmented, so there is no single “official” lore answer; multiple “001 proposals” and tales offer competing origin stories.

Quick Scoop style recap

  • Real-world creator:
    • First SCP (SCP‑173) written by Wesley “Moto42” Williams on 4chan in 2007.
  • Franchise creation:
    • The SCP Foundation universe is a community-driven, Creative Commons project built by many authors on the SCP Wiki since 2008.
  • Lore founder(s):
    • Depending on which story you read, founders may include characters like Aaron Siegel or shadowy groups that merged into the Foundation, but none is universally canonical.

TL;DR:
In real life, SCP was kicked off by Wesley “Moto42” Williams with SCP‑173 in 2007, then developed by a large online writing community; in the fiction, the Foundation’s founder is deliberately ambiguous and varies by story.
