S.T.A.R. Labs (Earth-1: Pre-Crisis)

Scientific Technological Advanced Research Laboratories, or simply S.T.A.R. Labs is a research facility.

Founding
The S.T.A.R. Laboratories was found in 2000 by Eobard Thawne who disguised as Harrison Wells after stealing the idea of Harrison Wells and Tess Morgan.

Particle accelerator explosion
In 2013, Eobard built a particle accelerator and activated it on December 11, 2013. However, it exploded and caused numerous people to gain superhuman powers. Eobard later took Barry, who was struck by lightning during the explosion. Eobard, along with only two of his employees, took care of Barry during his coma for nine months. During the time, S.T.A.R. Labs was shut down by the government. After Barry woke up, they realize he gained superhuman speed and helped him becoming a superhero.

Under Barry Allen's ownership
After Eobard's true identity was revealed to the team, Eobard filmed a confession of the murder of Nora Allen and transferred the ownership to Barry Allen. Barry later owned the labs until the destruction in 2017 caused by Savitar and his leave to the Speed Force.

Original timeline
In the original timeline, it was founded by Harrison Wells and Tess Morgan in the year of 2020 as well as the particle accelerator.
