Solomon Nunes de Carvalho

Solomon Nunes Carvalho (April 27, 1815 – May 27, 1897) was an American painter, photographer, author and inventor. He may be best known as an explorer who traveled through the territory of Kansas, Colorado and Utah with John C. Frémont on his fifth expedition. Many famous images of the Old West are based on images he made, although many others have been lost or confused with those taken by Mathew Brady and other contemporaries.
