Blount was there during World War II. Her work with amputees led her to think about ways she could help them. She had a lot of patients that had trouble eating. So she built a device that would help injured patients to eat. When the patient wanted more food they just signaled the machine by biting down on a switch that would send you the next mouth full. All the money she made from the device was sent to charity. She also invented the Disposable Cardboard Emesis Basin.

      She knew Thomas  Edison. They discussed her inventions and what else she could  do. The American Veteran's Administration didn't want to support her so she went to the French. They liked her invention. They  thanked her for  inventing something that is safer and helped prevent diseases. She showed that "a black woman can invent something to benefit".

Ever since she was a young girl and was punished for writing with her left hand, Blount was interested in handwriting. Her response to being punished was to learn how to write with her right hand, her mouth and her toes. Her work with the handicapped  led her to see that there were some things about writing that never changed  A couple of years later she began her own business as a forensic scientist. She was eighty three. She became a well known handwriting expert. In her business she used lots of her training to help her research about African Americans slave papers and war documents. She also worked on Native- American treaties. Blount helped out with "special investigations" for law enforcement.  She was called "Mama Bessie" when she went to London to study at Scotland Yard. This was a name she liked to be called.   Bessie Blount Griffin died on December 30, 2009 at the age of ninety four.
