Known as "John of the Mountains" and "Father of the National Parks", was an influential Scottish-American naturalist, author, environmental philosopher, glaciologist, and early advocate for the preservation of wilderness in the United States of America
The mountains are calling and I must go
In every walk with Nature one receives far more than he seeks
The world's big and I want to have a good look at it before it gets dark

Radium is not to enrich any one. It is an element; it is for all people
Every moment of light and dark is a miracle
Science knows no country because it is the light that illuminates the world
All truths are easy to understand once they are discovered; the point is to discover them
