Otis F. Boykin

He was responsible for inventing the wire precision resistor. This type of resistor is used in radios and televisions. He invented another resistor that was more resilient and inexpensive to manufacture two years later. A list of his other inventions include a chemical air filter, a burglarproof cash register, a control unit for pacemakers, and other types of resistors used in computers and guided missile systems. He was born in Dallas, Texas and graduated from Fisk College in Tennessee. He attended the Illinois Institute of Technology in Chicago yet did not graduate. This did not; however, deter him from inventing.

Dr. Patricia Bath

Ophthalmologist and inventor are just two names attributed to Mrs. Bath. She is recognized for her development of the Cataract Laserphaco Probe, which uses a laser's energy to vaporize a cataract and damaged lens and remove it from the eye.

She currently has four US patents involving the Cataract Laserphaco Probe as well as various other patents internationally.
