Circa 5 years ago I found biographical data about Benjamin B. Hill, an inventor who lived in Philadelphia.
Yesterday (17 March 2015), I was able to find some data about his patents & inventions, but very little biographical data.
Might there be a Web archive containing data no longer directly available via a search?
