WOMEN INVENTORS INDEX - 1790-1895
Protections are granted to inventors under Article I, Section 8 of the U.S. Constitution that permit the inventor to exclude others from making, using or selling the invention for a restricted period of time. These protections are called patents. Patent records give a picture of the concerns and economic operations at a particular place and at a particular point in time.
The earliest patent granted to a woman was awarded Dec. 8, 1808 to Hazel Irwin of Boston, Ma., although the U.S. awarded the first patent in 1790. This index covers the years 1808-1895 and lists only women inventors. It is based on the publication Women Inventors to whom patents have been granted by the United States Government, 1790-1895. U.S. Patent Office, 1888-1895. I23.5:W84
If you would like to see full text of these patents, search by the Patent Number at The U.S. Patent and Trademark Office web page. Items beginning with U are numbers which I created to identify part of the unnumbered patent series before 1837. Some are available on microfilm from any Patent Depository Library. Numbers beginning with D are design patents and numbers beginning with X are early patents. Both D and X patents are available at the U.S. Patent and Trademark Office web page.
The data on this page is arranged by Inventor(s), by person or company to whom the patent was assigned, by subject category and by State. Each patent has a representative drawing attached, if available. Searching is also available by Inventor's Last Name, Keyword in title and Place. If there is no information a blank screen will appear.
The column to the left shows some analysis of the data in these files.
Not all current states are represented. Some States joined the Union after 1895.
