In 1843, he published Historical Collections of the State of Pennsylvania. He came to California in 1849, and engaged in civil and mining engineering at San Jose, New Almaden, Folsom and Oakland.

As well, it contained a series of wonderful images (produced by Sherman as well) of all parts of the Keystone State.
