Beulah Henry was nicknamed "Lady Edison" because she is credited with over 100 inventions that made daily life easier. In 1912, her first invention was a vacuum-sealed ice cream freezer (Patent #1,037,762.) Henry was such a prolific inventor that she was granted 49 United States Patent and Trademark Office patents.
An interesting invention of hers was an umbrella with an interchangeable snap-on covers. These coordinated with the user's outfit. Wouldn't you love to have one of these!
