| Rachel Zimmerman |
| Rachel Zimmerman was twelve years old when she invented a program for computers called Blissymbols. The Blissymbol program helps mute people communicate to other people in the same room. The Blissymbols program started out as a school science fair project and ended up at the World Exhibition of Achievement of Young Inventors. She used a computer, monitor, keyboard, mouse, and, of course, wires. It took one to two years to invent. |
