The first photographic portrait of a human being. October or November 1839. A daguerreotype self-portrait by Robert Cornelius, an American son of Dutch immigrants, who worked in Philadelphia. Even one generation in, Americans look American.
His hair surely wasn’t tousled because he had just woken up. This was an important day, after all. It is deliberately unbrushed: the style derives from the more artfully windswept, unwigged heads that we see in paintings of the Napoleonic era and just afterwards. Their subjects would often press a spit curl against their foreheads, and there is even a derivative of that in this self-portrait.
