Daguerreotypes were the first commercially successful photographic process. There were widely used in the mid 1800's. The process was cumbersome, expensive & inefficient. Eventually, they were superseded in the marketplace by other methods of photography. What was good about them? Well apparently, the image quality of a Daguerreotype is so high that one can use a microscope to find hidden detail on them. This article in Wired Magazine has more about them....

President's Day is a sort of a misnomer. This February holiday is still officially called Washington's Birthday. In recent decades it has come to be known as Presidents Day, but it was never changed to that. Some states officially call it Presidents' Day, to make note of the fact that the beloved President Lincoln, was also born in February.
