Invention: Portable Fax, Touch Tone Telephone, Solar Cell, And The Fiber Optic Cables
Dr. Shirley Jackson.
Jackson started to conduct successful experiments in theoretical physics and then started to use her knowledge in physics to start making advances in telecommunications while working at Bell Laboratories. These inventions include developments in the portable fax, touch tone telephone, solar cell, and the fiber optic cables used to provide clarity in overseas telephone calls. She has also helped make possible Caller ID and Call Waiting.
a theoretical physicist and famous black inventor, She first developed an interest in science and mathematics during her childhood and conducted experiments and studies, such as those on the eating habits of honeybees. She followed this interest to the Massachusetts Institute of Technology (MIT) where she received a bachelors, masters, and doctoral degree, all in the field of physics. In doing so she became the first African-American woman to acquire a Ph.D. from MIT.
