Asger Oluf Jorn (3 March 1914–1 May 1973) was a Danish painter, sculptor, ceramic artist, and author. He was a founding member of the avant-garde movement COBRA and the Situationist International. He was born in Vejrum, in the northwest corner of Jutland, Denmark and baptized Asger Oluf Jørgensen.

The largest collection of Asger Jorn's works—including his major work Stalingrad—can be seen in the Museum Jorn, Silkeborg, Denmark.

He was the second oldest of six children, an elder brother to Jørgen Nash. Both his parents were teachers. His father, Lars Peter Jørgensen, was a fundamentalist Christian who died when Asger was 12 years old in a car crash. His mother, Maren, née Nielsen, was more liberal but nevertheless a deeply committed Christian. This early heavy Christian influence had a negative effect on Asger who began progressively to inwardly rebel against it, and more generally against other forms of authority.

In 1929, aged 15, he was diagnosed with tuberculosis although he made a recovery from it after spending 3 months on the west coast of Jutland. By the age of 16 he was influenced by Nicolai Grundtvig, and although he had already started to paint, Asger enrolled in the Vinthers Seminarium, a teacher training college in Silkeborg where he paid particular attention to a course in Nineteenth century Scandinavian thought. Also at about this time Jorn became the subject of a number of oil paintings by the painter Martin Kaalund-Jørgensen, which encouraged Jorn to try his hand in this medium.

Paul Jackson Pollock (January 28, 1912 – August 11, 1956), known as Jackson Pollock, was an influential American painter and a major figure in the abstract expressionist movement. He was well known for his uniquely defined style of drip painting.

During his lifetime, Pollock enjoyed considerable fame and notoriety. He was regarded as a mostly reclusive artist. He had a volatile personality, and struggled with alcoholism for most of his life. In 1945, he married the artist Lee Krasner, who became an important influence on his career and on his legacy.

Pollock died at the age of 44 in an alcohol-related car accident. In December 1956, the year of his death, he was given a memorial retrospective exhibition at the Museum of Modern Art (MoMA) in New York City, and a larger more comprehensive exhibition there in 1967. More recently, in 1998 and 1999, his work was honored with large-scale retrospective exhibitions at MoMA and at The Tate in London.

In 2000, Pollock was the subject of an Academy Award–winning film Pollock directed by and starring Ed Harris.

A hunter-gatherer or forager society is one in which most or all food is obtained from wild plants and animals, in contrast to agricultural societies which rely mainly on domesticated species.

Hunting and gathering was the ancestral subsistence mode of Homo, and all modern humans were hunter-gatherers until around 10,000 years ago. Following the invention of agriculture hunter-gatherers have been displaced by farming or pastoralist groups in most parts of the world. Only a few contemporary societies are classified as hunter-gatherers, and many supplement, sometimes extensively, their foraging activity with farming and/or keeping animals.

The earliest humans probably lived primarily on scavenging, not actual hunting. Early humans in the Lower Paleolithic lived in mixed habitats which allowed them to collect seafood, eggs, nuts, and fruits besides scavenging. Rather than killing large animals themselves for meat, they used carcasses of large animals killed by other predators or carcasses from animals that died by natural causes.
