John Muir 
My First Summer in the Sierra [EPUB ebook] 
"The sun shines not on us but in us."

John Muir was born in Scotland on April 21st, 1838. His Father wanted his children to have a stricter Religious upbringing and therefore moved the family to the United States. John Muir is perhaps known today as the most pre-eminent naturalist and advocate for the preservation of much of the western United States. Today being an environmentalist is laudable but in Muir’s days the country was there to be exploited but by hard work and lobbying Muir did much to turn such beautiful areas as Yosemite into protected National Parks. His writing is not only an invaluable guidebook to these unspoilt places but also a hymn to their spirituality. As a keen scientific mind he helped to push the understanding of nature forward by observing and writing upon the glaciers and their actions in eroding and shaping much of the land. Muir helped to also create The Sierra Club, which he led for many years, on projects to preserve these and other areas of outstanding natural beauty. He was equally adept at persuading politicians, from Presidents to local State officials, and the common man to come together in the defence of Nature.
