I apologise in advance for an offensive question!

In 1859, Martha Coston invented a system of maritime signal flares based on color and pattern. Because radio invented in 1895 by Guglielmo Marconi. By using various color combinations, these flares made ship-to-ship and ship-to-shore communication possible.

Michael Nesmith's (the Monkees) mom created Liquid Paper in her kitchen in 1951

Ah, my computer coughed up my original comment. But I see everyone gave you supremo answers to you question. I would like to add that in the past a woman was not issued a patent. Therefore many women let a man apply for the patent of her invention and he got the credit too. Thousands of inventions have been incorrectly credited to men. So there's something to think about.

remember marie curie who discovered the element curium in science. include that in the list. other than that, i dont know yet but im sure there are if i try to research the net but im busy right now my friend so i guess marie curium is enough. i think most inventions or discovery were made by men and im p roud of it because im a man.hehehehe.
