Invisible glass

Year of invention: 1935

Who invented it: Katherine Blodgett  

After completing her Ph. D, Blodgett started her research on the impact of a single molecule coating on a glass.

During her research, she discovered that a coating of a thin film can completely free the glass from any kind of reflection.

And this is how after months of research, she invented transparent glass, popularly known as the ‘invisible glass’ which can be used in cameras and telescopes for limiting reflection.

Interestingly, she was the first woman to be awarded the doctorate degree by the CambridgeUniversity.

White correction fluid

Year of invention: 1956

Who invented it: Bette Nesmith Graham

 

Bette Nesmith Graham with her sonBette Nesmith Graham was an employee at the Texas Bank and Trust in Dallas during the 1950’s.

In those days, she worked on an electric type writer and found it extremely difficult to erase mistakes.

One day, while returning home from office, she came across a painter who was erasing his errors with white colour paint.

After observing the artist and his work for a while, Graham realised that even she can use this technique while typing.

And, hence she decided to put some tempera water-based paint in a bottle and started using it with the help of a paint brush to erase mistakes while typing.

Graham secretly used her white correction paint for five years and eventually began marketing her typewriter correction fluid as "Mistake Out" in 1956.

The name was later changed to ‘Liquid Paper’ when she began her own company.

Circular Saw

Year of invention: 1813

Who invented it: Tabitha Babbitt

 Tabitha Babbitt was an American tool maker. She invented the circular saw after observing two labourers trying to cut wood with a long two-handled tool standing in opposite directions. The procedure looked very tedious to Babbitt.   

Being an efficient tool maker, she realised that a round blade could have been more efficient.  

After few months, she invented the first circular saw which was used in a saw mill in 1813.  

The saw was hooked up to a water powered machine to reduce efforts while cutting wood.

Dishwasher

Year of invention: 1886

Who invented it: Josephine Cochranemade

Cochrane was a popular rich woman who hosted parties frequently. She often hoped to create a machine which could wash plates for her.  

One day, she just measured the dishes, then built wire compartments, each specially designed to fit either plates, cups, or saucers.  

The compartments were placed inside a wheel that lay flat inside a copper boiler. A motor turned the wheel while hot soapy water squirted up from the bottom of the boiler and rained down on the dishes.  

After this invention, Cochrane became so famous that she started getting orders for her dish washing machine from restaurants in Illinois. She later patented her invention.
