I've become interested in the history of photography. In the earliest years, exposure times were several hours, and the subject had to remain completely still, so portrait photographs were impossible. Within a few years, the exposure time had been reduced to under 10 minutes. That was still a long time to remain still, and clamps were used to prevent people from blurring the picture by moving, but it was short enough to allow portrait photographs. Robert Cornelius was one of scientists who found a way to shorten exposure times to a few minutes. In 1839, Cornelius took what is thought to be the first photograph of a human face. It is also the first self-portrait. Here is the photo. My first reaction wasn't, wow, that's an incredible contribution to mankind. It was, damn he's hot! So hot that he invented portrait photography to document it for future generations. It turns out that there are several hot long-dead guys. Some smart long-dead guys: Oliver Wendell Holmes Before the age of photography, but I've always thought that Alexander Hamilton of $10 bill fame was very good looking. And as always, there were some bad but hot guys: Lewis Powell--conspired to assassinate Lincoln, stabbed Secretary of State William Seward and his bodyguard, and bludgeoned Seward's son, and subject of the most awesome mugshots ever. Louis Lingg--anarchist who advocated violence and terrorism and created the bombs used in the Haymarket Square Bombing Do you have any crushes on long-dead guys?
