Terry A. Davis (1969–2018) began experiencing regular manic episodes in 1996, leading him to numerous stays at mental hospitals.
Initially diagnosed with bipolar disorder, he was later declared schizophrenic and remained unemployed for the rest of his life.
He suffered from delusions of space aliens and government agents that left him briefly hospitalized for his mental health issues.
After experiencing a self-described "revelation", he proclaimed that he was in direct communication with God, and that God told him the operating system was for God's third temple.

Davis began developing TempleOS circa 2003.
One of its early names was the "J Operating System" before renaming it to "LoseThos", a reference to a scene from the 1986 film Platoon.
In 2008, Davis wrote that LoseThos was "primarily for making video games. "
It has no networking or Internet support.
As far as I'm concerned, that would be reinventing the wheel".
Another name he used was "SparrowOS" before settling on "TempleOS".
In mid-2013, his website announced: "God's temple is finished.
Now, God kills CIA until it spreads  [sic]."
 Davis died after being hit by a train on August 11, 2018.
