Lady Edison

I was recently reading the July-August 2025 issue of "The Science Teacher", a publication of the National Science Teaching Association. In this issue, I read the section, "Right to Source" written by Jessica Fries-Gaither. She wrote an article entitled, "Exploring Everyday Inventions with "Lady Edison"." Beulah Louse Henry (1887-1973) was a self-taught inventor, earning 49 patents and creating over 100 inventions over a 50 year period, including a vacuum ice-cream freezer, a bobbinless sewing machine, and an umbrella with color-coordinated snap-on covers.
