It seems I did way too many photographers but still need to do Ansel Adams

Born in 1902, in San Fransisco, Adams grew up loving and appreciating nature, which is what guided him to photography and becoming an influential member of the Sierra Club. He became the club's official photographer in 1927 and helped lobby Congress for the preservation of many parks. In 1968 Adams earned the Conservation Service Award. He died in Monterey, California, in 1984.
