Fact Check: Physicist Shirley Jackson Did NOT Invent Fiber-Optic Cables, Touch-Tone Phone Or Caller ID

Did theoretical physicist Shirley Jackson invent fiber-optic cables, the touch-tone phone and caller ID? No, that's not true: All of these were invented by other people. Although her professional accomplishments and accolades are many, she did not invent those telecommunication advances as a post claims, nor did she invent call waiting, the portable fax machine or the solar cell, which are also commonly attributed to her in social media memes.
