for science, did you learn anything about eli whitney in school /BESIDES/ the fact that he patented the cotton gin
i ask because most of his papers are housed at yale & the only biographies i found written about him [that are /not/ childrens books] once i went searching were from 1832 & 1956
i& #39;ve got two American history textbooks, copyrights 1935 & 1995, and they both mention essentially the same thing [though i was surprised to see 1995 mention interchangeable parts]

this isn& #39;t a conversation about textbooks, though it could be, but it& #39;s mostly a conversation about how when someone wants to hide something about history, it& #39;s surprisingly easy, especially when we have something like the cotton gin to focus on
that& #39;s not saying eli whitney hid something but that is to say that he also invented a bunch medical devices to ease his pain from prostrate cancer but since 19th century doctors were so squeamish & his family thought them inappropriate, he was forbidden from describing them
