Mathew Brady quotes:

No one will ever know what I went through to secure those negatives. The world can never appreciate it. It changed the whole course of my life.

From the first, I regarded myself as under obligation to my country to preserve the faces of its historic men and mothers

My greatest aim has been to advance the art of photography and to make it what I think I have, a great and truthful medium of history.

The camera is the eye of history.

I had to go. A spirit in my feet said 'go,' and I went.
