Amazing. If someone who was born in another country and now lives in the usa creates something they are americans, but if they do something bad or whatever they are suddenly immigrants, limeys, krauts, spicks, etc.
Hypocrite

Not at all, what are you talking about? By that logic Einstein was still German, despite working to fight against them for years and years.
Nope, flawed logic. AMERICAN of German descent, just like Madonna is a Brit of American descent.

you forgot other great american inventions
1896 Automatic Hat.
James Boyle, of Washington, invents a hat that tips automatically
1924 Gas Chamber Execution.
In an effort to make capital punishment more humane, the State of Nevada introduces death by gas chamber. Convicted murderer Gee John takes 6 minutes to die.

Einstein also fought against Nazi Germany because he was jewish, and as regards Madonna, please, take her back.
Oh, about my original comment? Try reading it again.

Saw your claim about the camera there toxicity.
Thought you might like to read this. Copied it off wiki for you, interesting how your sights definition stops at the american.
The forerunner to the camera was the camera obscura. The camera obscura is an instrument consisting of a darkened chamber or box, into which light is admitted through a double convex lens, forming an image of external objects on a surface of paper or glass, etc., placed at the focus of the lens.
The camera obscura was first invented by the Iraqi scientist Ibn al-Haytham (Alhazen) as described in his Book of Optics (1015-1021).
English scientist Robert Boyle and his assistant Robert Hooke later developed a portable camera obscura in the 1660s.
The first camera that was small and portable enough to be practical for photography was built by Johann Zahn in 1685, though it would be almost 150 years before technology caught up to the point where this was practical. Early photographic cameras were essentially similar to Zahn's model, though usually with the addition of sliding boxes for focusing. Before each exposure, a sensitized plate would be inserted in front of the viewing screen to record the image. Jacques Daguerre's popular daguerreotype process utilized copper plates, while the calotype process invented by William Fox Talbot recorded images on paper.

The first permanent photograph was made in 1826 by Joseph Nicéphore Niépce using a sliding wooden box camera made by Charles and Vincent Chevalier in Paris. Niépce built on a discovery by Johann Heinrich Schultz (1724): a silver and chalk mixture darkens under exposure to light. However, while this was the birth of photography, the camera itself can be traced back much further. Before the invention of photography, there was no way to preserve the images produced by these cameras apart from manually tracing them.
The development of the collodion wet plate process by Frederick Scott Archer in 1850 cut exposure times dramatically, but required photographers to prepare and develop their glass plates on the spot, usually in a mobile darkroom. Despite their complexity, the wet-plate ambrotype and tintype processes were in widespread use in the latter half of the 19th century. Wet plate cameras were little different from previous designs, though there were some models, such as the sophisticated Dubroni of 1864, where the sensitizing and developing of the plates could be carried out inside the camera itself rather than in a separate darkroom. Other cameras were fitted with multiple lenses for making cartes de visite. It was during the wet plate era that the use of bellows for focusing became widespread.
The first colour photograph was made by James Clerk Maxwell, with the help of Thomas Sutton, in 1861
Oh and regarding Talbot's original instructions, there is no mention made of hyposulphite of soda as a fixing agent; that was first used by John Herschel in February 1840. Also found on Wiki

Don't know about that

I actually tried this stupid shit!!
