Paul Oppenheim (June 17, 1885 – June 22, 1977)
In collaboration with Reichenbach, Oppenheim contributed greatly to these endeavors. Together they crafted what came to be known as the Verification Principle, also referred to as the Falsifiability Thesis. According to this principle, a statement can only be deemed scientific if there exists potential evidence either confirming or disproving its truth value. The Verification Principle suggests that all scientific claims must strive towards being potentially falsifiable.
