My grandfather invented the cold air balloon...
It never really took off.
Kodak camera patentIn 1888, George Eastman was issued a landmark U.S. patent No. 388,850 for his box camera. On the same date, he registered the trademark name: Kodak. The Eastman Kodak company was formed 24 Apr 1888. This design was the first Kodak mass-produced camera, and brought photography to the mass market. As described in its advertising, the operation was simple: "Pull the String, Turn the Key, Press the Button." Now anyone could take pictures family, events, indoor and outdoor scenes, and vacations, without needing special skills. Only 22-ounces in weight, it required no tripod or table for support. It used a fixed-focus lens which was still fast enough to take practically instantaneously exposures. Its roll film was enough to take 100 pictures, each 2½ inches diameter.«* |
