George P. (George Perkins) Marsh

Born in Woodstock, Vermont, in 1801, George Perkins Marsh became one of the most wide-ranging American thinkers of his time. He worked as a lawyer, served in the U.S. House of Representatives, and later represented the United States abroad, including long diplomatic service in Italy.

Marsh is remembered most strongly for Man and Nature (1864), a book that warned that deforestation, overgrazing, and other human actions could permanently reshape the environment. That argument made him an important early figure in the history of conservation and environmental thought.

He was also known for his deep interest in languages, history, and literature, which gave his writing an unusually broad, learned character. Marsh died in 1882, but his ideas continued to influence later readers who were trying to understand the relationship between people and the land.
