Beginning with predominantly agricultural and domestically focused inventions, Wyoming women’s patents have grown to include industrial, scientific, and technical areas. Here are a few samples of historical inventions by Wyoming women. Check out more Wyoming inventors in the Wyoming Inventors Database offered by the Wyoming State Library.
