George Washington Carver

===Peanut products===
[[Dennis Keeney]], director of the [[Leopold Center for Sustainable Agriculture]] at [[Iowa State University]], wrote in the ''Leopold Letter'' (newsletter):

<blockquote>Carver worked on improving soils, growing crops with low inputs, and using species that fixed nitrogen (hence, the work on the cowpea and the peanut). Carver wrote in 'The Need of Scientific Agriculture in the South': "The virgin fertility of our soils and the vast amount of unskilled labor have been more of a curse than a blessing to agriculture. This exhaustive system for cultivation, the destruction of forest, the rapid and almost constant decomposition of organic matter, have made our agricultural problem one requiring more brains than of the North, East or West.<ref>Fishbein, Toby.

Carver worked for years to create a company to market his products. The most important was the Carver Penol Company, which sold a mixture of [[creosote]] and peanuts as a [[patent medicine]] for respiratory diseases such as [[tuberculosis]]. Sales were lackluster and the product was ineffective according to the [[Food and Drug Administration]].<ref>{{cite book|author=McMurry|title=George Washington Carver|url=https://books.google.com/books?id=hlMkIgwg9KEC&pg=PA195|date=1982|pages=195–96|publisher=Oup USA |isbn=9780195032055|access-date=March 4, 2016|archive-date=August 1, 2020|archive-url=https://web.archive.org/web/20200801221328/https://books.google.com/books?id=hlMkIgwg9KEC&pg=PA195|url-status=live}}</ref> Other ventures were The Carver Products Company and the Carvoline Company. Carvoline Antiseptic Hair Dressing was a mix of peanut oil and [[lanolin]]. Carvoline Rubbing Oil was a [[peanut oil]] for massages.

Carver is often mistakenly credited with the invention of [[peanut butter]].<ref name="NPB">{{Citation |author=National Peanut Board |author-link=National Peanut Board |title=Who Invented Peanut Butter? |url=http://nationalpeanutboard.org/peanut-info/who-invented-peanut-butter.htm |access-date=November 24, 2016 |postscript=. |archive-date=November 25, 2016 |archive-url=https://web.archive.org/web/20161125044806/http://nationalpeanutboard.org/peanut-info/who-invented-peanut-butter.htm |url-status=live}}</ref> By the time Carver published "How to Grow the Peanut and 105 Ways of Preparing it For Human Consumption" in 1916,<ref>[http://nationalpeanutboard.org/the-facts/george-washington-carver/ "George Washington Carver"] {{Webarchive|url=https://web.archive.org/web/20151101124402/http://nationalpeanutboard.org/the-facts/george-washington-carver/ |date=November 1, 2015}}, National Peanut Board.</ref> many methods of preparation of peanut butter had been developed or patented by various pharmacists, doctors and food scientists working in the US and Canada.<ref>{{cite web|url = http://pdfpiw.uspto.gov/.piw?Docid=00306727&homeurl=http%3A%2F%2Fpatft.uspto.gov%2Fnetacgi%2Fnph-Parser%3FSect1%3DPTO2%2526Sect2%3DHITOFF%2526p%3D1%2526u%3D%25252Fnetahtml%25252FPTO%25252Fsearch-bool.html%2526r%3D1%2526f%3DG%2526l%3D50%2526co1%3DAND%2526d%3DPALL%2526s1%3D0306727.PN.%2526OS%3DPN%2F0306727%2526RS%3DPN%2F0306727&PageNum=&Rtype=&SectionNum=&idkey=NONE&Input=View+first+page|title = US Patent #306727|access-date = October 20, 2015|archive-date = April 5, 2017|archive-url = https://web.archive.org/web/20170405145402/http://pdfpiw.uspto.gov/.piw?Docid=00306727&homeurl=http%3A%2F%2Fpatft.uspto.gov%2Fnetacgi%2Fnph-Parser%3FSect1%3DPTO2%2526Sect2%3DHITOFF%2526p%3D1%2526u%3D%25252Fnetahtml%25252FPTO%25252Fsearch-bool.html%2526r%3D1%2526f%3DG%2526l%3D50%2526co1%3DAND%2526d%3DPALL%2526s1%3D0306727.PN.%2526OS%3DPN%2F0306727%2526RS%3DPN%2F0306727&PageNum=&Rtype=&SectionNum=&idkey=NONE&Input=View+first+page|url-status = live}}</ref><ref>{{cite web|url = http://pdfpiw.uspto.gov/.piw?docid=00604493&PageNum=1&IDKey=611D5B869ACB&HomeUrl=http://patft.uspto.gov/netacgi/nph-Parser?Sect2=PTO1%2526Sect2=HITOFF%2526p=1%2526u=%25252Fnetahtml%25252FPTO%25252Fsearch-bool.html%2526r=1%2526f=G%2526l=50%2526d=PALL%2526S1=0604493.PN.%2526OS=PN/0604493%2526RS=PN/0604493|title = US Patent #604493|access-date = March 11, 2022|archive-date = April 5, 2017|archive-url = https://web.archive.org/web/20170405172017/http://pdfpiw.uspto.gov/.piw?docid=00604493&PageNum=1&IDKey=611D5B869ACB&HomeUrl=http%3A%2F%2Fpatft.uspto.gov%2Fnetacgi%2Fnph-Parser%3FSect2%3DPTO1%2526Sect2%3DHITOFF%2526p%3D1%2526u%3D%25252Fnetahtml%25252FPTO%25252Fsearch-bool.html%2526r%3D1%2526f%3DG%2526l%3D50%2526d%3DPALL%2526S1%3D0604493.PN.%2526OS%3DPN%2F0604493%2526RS%3DPN%2F0604493|url-status = live}}</ref><ref>{{cite web |author=Innovate St. Louis |url=http://www.innovatestl.org/stlouishistory.html |title=Innovation in St. Louis History – Innovate St. Louis |publisher=Innovatestl.org |date=August 25, 2011 |access-date=December 18, 2011 |url-status=dead |archive-url=https://web.archive.org/web/20111227090829/http://www.innovatestl.org/stlouishistory.html |archive-date=December 27, 2011}}</ref> The [[Aztecs]] were known to have made peanut butter from ground peanuts as early as the 15th century.
