Richard Misrach (born in Los Angeles, California in 1949) is an American photographer known for his photographs of human intervention in landscapes and for his influence in large-scale color photography. His works are represented in more than fifty major museum collections around the world.

Richard Misrach has worked over 40 years using landscapes. His best known series, Desert Cantos, is a ongoing series and a multi-faceted study of man’s relationship towards his place on earth. He has other bodies of work that include his thoughts and study of weather, time, color and light in his photographs of the Golden Gate, his records of the industrial corridor down the Mississippi River known as Cancer Alley, and an aerial viewpoint of human interface and isolation called On the Beach.In his most recent projects, they depart from his usual work. He has researched new technology in digital capture and printing. Misrach uses the negative as an end in itself and digitally creates images with astonishing detail and color. More recently, he built a powerful narrative out of images of graffiti produced in the aftermath of Hurricane Katrina, made with a 4-megapixel pocket camera.

David Ross Brower (July 1, 1912 – November 5, 2000) was a prominent environmentalist and the founder of many environmental organizations, including the Sierra Club Foundation, the John Muir Institute for Environmental Studies, Friends of the Earth (1969), the League of Conservation Voters, Earth Island Institute (1982), North Cascades Conservation Council, and Fate of the Earth Conferences. From 1952 to 1969 he served as the first Executive Director of the Sierra Club, and served on its board three times: from 1941–1953; 1983–1988; and 1995-2000. As a younger man, he was a prominent mountaineer.

Brower was born in Berkeley, California. He was married to Anne Hus Brower (1913 – 2001) whom he met when they were both editors at the University of California Press in Berkeley.

Most notably of Brower's children, Kenneth Brower would go on to author a number of books, most notably The Starship and the Canoe about Freeman Dyson and his son George Dyson.

James Arthur "Jim" Ratcliffe (born 1952) is a chemical engineer turned financier and industrialist. According to the 2010 Sunday Times Rich List, he is one of the richest people in the United Kingdom.

Born in Manchester, Ratcliffe graduated from the University of Birmingham with a degree in chemical engineering in 1974. His first job was with oil giant Esso, but he decided to broaden his skills into finance by studying management accounting and taking an MBA at London Business School.

Ratcliffe is the chairman and chief executive officer of the Ineos chemicals group, of which he owns two-thirds, and which has been estimated to have a turnover of $44bn. He does not have a high public profile, and has been described by the Sunday Times as "publicity shy".

Using high-yield debt to finance his deals, Ratcliffe started buying unwanted operations from groups such as ICI and BP, selecting targets based on their potential to double their earnings over a 5-year period. In 2006 Ineos bought BP's refining and petrochemical arm, which brought the Grangemouth Refinery into Ineos' control.
