Learning From Teachers

Eight-year-old Sally brought her report card home from school. Her marks were good...mostly A's and a couple of B's.
However, her teacher had written across the bottom: "Sally is a smart little girl, but she has one fault. She talks too much in school. I have an idea I am going to try, which I think may break her of the habit."
Sally's dad signed her report card, putting a note on the back: "Please let me know if your idea works on Sally because I would like to try it out on her mother."

Stenotype

In 1876, the stenotype was patented by John C. Zachos of New York City (No. 175,892). This was the first U.S. patent for a device for printing legible text in the English alphabet at a high reporting speed, which he called a "typewriter and phonotypic notation." The type was fixed on eighteen shuttle bars, two or more of which may be simultaneously placed in position. The impression was given by a plunger common to all bars. He called his new system of shorthand "stenophonotypy."*
