de Forest Research was a research and consultation company that was owned and operated by Kellam de Forest.
de Forest also came up with the idea of silicon-based life for "The Devil in the Dark", as the original chemical substance in Gene L. Coon's script deemed to be inaccurate. (Inside Star Trek - The Real Story [page number? • edit])
Possibly, de Forest made the suggestion to change the Latin names of ancient gods to their original Greek ones, in the script of "Who Mourns for Adonais?". [1]
In another example, a report from de Forest noted the error of the use of "bisexual" in the script for "The Trouble with Tribbles", but it was never changed in the script.
Also among the facts de Forest corrected was the Native American tribes whose mixture the inhabitants were in "The Paradise Syndrome". de Forest furthermore corrected the costumes and props of the Indians accordingly, but they were not changed in the filmed episode.

He sold the company in 1997[2], which currently operates under the name "Act One Script Clearance / de Forest Research".[3]
