"Long before Stephen Bannon was CEO of Donald Trump's presidential campaign, he held a much different job - as the acting director of Biosphere 2, a $200 million scientific research facility in the mountains outside Tucson, Arizona. ... Bannon left Biosphere 2 after two years, and the project was taken over by Columbia University"
"... the science project, which started with eight people living in a closed habitat, disintegrated amid earthly squabbles, lawsuits and allegations of sexual harassment involving Stephen Bannon. The former Biosphere 2 consultant went from dreams of space colonization to courtroom drama after he was accused in separate court filings of threatening one female employee and harassing another."
Biosphere 2, Wikipedia
"After a successful turnaround by Bannon & Co. in December 1995 the Biosphere 2 owners transferred management to Columbia University of New York City which embarked on a successful eight-year run at the Biosphere 2 campus. Columbia ran Biosphere 2 as a research site and campus until 2003. Subsequently, management reverted to the owners."
