Inventor
During much of this time, and afterwards, Porter was a prolific inventor. During 1825-1826 he published four editions of A Select Collection of Valuable and Curious Arts, and Interesting Experiments. He built a portable camera obscura that let him make silhouette portraits in less than 15 minutes. (He charged 20 cents apiece for them.) He experimented with a wind-powered gristmill, a washing machine, a corn sheller, a fire alarm, a rope-making machine, and a camera. He invented clocks, railway signals, churns, a distance measuring appliance, a horsepower mechanism, a churn, a life preserver, a cheese press, and a revolving rifle. Typical of his inability to capitalize on his genius, he sold the rights to the revolving rifle to Samuel Colt for $100, and the design was permanently shelved.

Famous quotes containing the word inventor:
“It is beyond a doubt that during the sixteenth century, and the years immediately preceding and following it, poisoning had been brought to a pitch of perfection which remains unknown to modern chemistry, but which is indisputably proved by history. Italy, the cradle of modern science, was at that time, the inventor and mistress of these secrets, many of which are lost.”
—Honoré De Balzac (1799–1850)
“The public values the invention more than the inventor does. The inventor knows there is much more and better where this came from.”
—Ralph Waldo Emerson (1803–1882)
“I have defeated them all.... I was left with some money to battle with the world when quite young, and at the present time have much to feel proud of.... The Lord gave me talent, and I know I have done good with it.... For my brains have made me quite independent and without the help of any man.”
—Harriet A. Brown, U.S. inventor and educator. As quoted in Feminine Ingenuity, ch. 8, by Anne L. MacDonald (1992)
