THINGS WOMEN INVENT PART 4

Do not miss Part 3 from ... HERE

#16 Patricia Bath, M.D.: Laser Cataract Surgery Device 

She's the first African-American female doctor to patent in 1988, a new method of removing cataracts. The medical laser instrument made the procedure more accurate and is termed the cataract Laserphacoprobe. Dr. Bath was also the first Black Female Surgeon appointed to UCLA in 1975. As a laser scientist and inventor, she has 5 patents on the laser cataract surgery device covering the United States, Canada, Japan, and Europe. 

#17 Ann Moore: The Snugli® Baby Carrier  

As a Peace Corps nurse during the 1960s in West Africa, Moore was inspired to create the Snugli®, as well as other kinds of specialized carrying cases. She'd seen African mothers carry their babies in fabric slings tied securely on their backs and she thought to try the same. But her baby daughter kept slipping. After much experimentation with a backpack, she modified and refined the design until it worked. 

#18 Lyda Newman: Improved Hairbrush 

While Newman was not the original inventor of the hair brush, her improvements to the brush made her a significant contributor to its evolution. She was among many who played a pivotal role in the development of hair-care products during the late 19th and early 20th centuries. 

#19 Patsy Sherman: Scotchgard™ Stain Repellent 

Sherman's role in the invention of Scotchgard™ was a "happy mistake". As a research chemist with 3M in 1953, a lab mishap with fluorochemicals lead her to a new discovery. An assistant accidentally dropped a bottle of synthetic latex that Sherman had made, it splashed onto the assistant's white canvas tennis shoes. The substance did not change the look of the shoes, and importantly, it couldn't be washed away by any solvents, and it repelled water, oil and other liquids.

#20 Marion Donovan: Disposable Diapers 

Debuting at Saks Fifth Avenue in 1949, was Donovan's first successful invention called "Boaters." It was a waterproof baby diaper cover that prevented diaper rash. Prior to this time she couldn't get manufacturers to work with "Boaters", so she struck out on her own. This inventive spirit led her to create the disposable diapers, Pampers® in 1961.
