| Feature for Today |
 On 12 Sep 1812, Richard M. Hoe was born, the American inventor who developed and manufactured the first successful rotary printing press (1846). His first patented idea came about ten years earlier, though it concerned the grinding of circular saws. He then turned his attention to what became is lifetime career—improving the productivity of the printing press to keep up with the demands caused by increasing circulation of newspapers and journals. His early Hoe's Double Cyclinder Press was admired for its ability to turn out about six thousand impressions per hour. With a gift for invention, he continually advanced the size and production speed of his presses. Later in life, he supplied a ten-cylinder steam press to the New York World. For more biography on the accomplishments of this significant inventor, Richard M. Hoe, see this chapter from Kings of Fortune (1888). |

| Quotations for Today | |
 | It occurred to me that if I could invent a machine - a gun - which could by its rapidity of fire, enable one man to do as much battle duty as a hundred, that it would, to a large extent supersede the necessity of large armies, and consequently, exposure to battle and disease [would] be greatly diminished. - Richard Jordan Gatling, American inventor (born 12 Sep 1818).  |
 | That one must do some work seriously and must be independent and not merely amuse oneself in life—this our mother [Marie Curie] has told us always, but never that science was the only career worth following. - Ir�ne Joliot-Curie, French physicist and physical chemist (born 12 Sep 1897). |
 | Shoe leather epidemiology. [Langmuir stressed that investigators go into the field to collect their own data and directly view the locale of a public health problem. His graduates wore lapel pins of a shoe with a hole in the sole.] - Alexander Langmuir, American epidemiologist (born 12 Sep 1910). |
