Boyle's law
In a series of experiments with his family friend, Richard Towneley, Henry Power discovered the relationship between the pressure and volume of a gas that later became known as Boyle's law. This relationship was outlined in "Experimental Philosophy." However, many may argue nevertheless that a pre-publication manuscript of "Experimental Philosophy" cited the hypothesis as the sole work of Richard Towneley. Boyle's mention of the theory preceded the publication of "Experimental Philosophy" by one year, which, combined with Boyle's promotion of the idea and his significant status as an aristocratic scientist, ensured the theory would be known as "Boyle's Law." Boyle attributed Towneley as the sole researcher, ensuring that Power's contributions were all but lost to history.
