September 1888: George Eastman Patents His Kodak Camera
Marking an anniversary before it slips downward the retention hole.
And it's yesteryear Vaclav Smil.
From IEEE Spectrum:
It was slow plenty for the amateur lensman to use, in addition to that made it the nearly of import photographic goggle box camera in history

By 1888, photographers had been fixing images on plates for to a greater extent than than half dozen decades, in addition to roughly of them produced impressive portraits, photojournalism, in addition to landscapes. But no 1 could attain such things easily....MORE
The starting fourth dimension prerequisite for effortless motion painting taking came inwards 1871, when Richard Maddox invented highly sensitive dry out plates—glass coated amongst gelatin emulsion. That pace eliminated the awkward coating-exposure-processing sequence that had to live on done on-site when using the wet-plate process.
But an entire suite of improvements all the same needed to live on made, in addition to they came from an unlikely innovator: George Eastman, a depository fiscal establishment clerk inwards Rochester, N.Y. In 1877, Eastman bought a photographic goggle box camera in addition to wet-plate gear to purpose on a trip to Santo Domingo. The trip cruel through, merely it prompted Eastman to experiment amongst novel emulsion coatings, in addition to inwards 1879 he patented a coating machine. In 1884 he replaced the drinking glass back upward amongst a negative stripping cinema made of 3 layers—paper, soluble gelatin, in addition to gelatin emulsion. In 1885 he added a convenient scroll holder.
The in conclusion pace came 130 years ago, on 4 September 1888, when Eastman was awarded United States of America Patent No. 388,850 for a small, handheld, easy-to-use camera. His fellowship had already begun making it 3 months earlier.
Eastman called the photographic goggle box camera a Kodak because he liked the band of it. It was a wooden rectangular prism 9.5 yesteryear 8.3 yesteryear 16.5 centimeters (3.75 by 3.25 yesteryear 6.5 inches) covered inwards polish dark leather. Its 57-millimeter lens had proficient close-focusing capabilities, allowing the lensman to focus on objects every bit unopen every bit 1.2 meters.
It wasn’t actually every bit slow to purpose every bit its advertisements claimed—“You press the button, nosotros attain the rest”—but it was slow enough. You pose the cinema inwards in addition to advanced it, in addition to later exposing all l or 100 frames (there was no exposure counter), you lot rewound it. Then, you lot had to send the entire photographic goggle box camera to Eastman’s manufacturing flora inwards Rochester to live on developed in addition to printed. The starting fourth dimension model terms U.S.A. $25 (more than $600 inwards 2018 terms)....
