Arno Peters (22 May 1916 – 2 December 2002) developed the Peters world map, based on the Gall–Peters projection.
Peters was a German historian born in Berlin on 22 May 1916. He began his career in Hollywood in the late 1930s, studying American filmmaking. After attaining his doctorate degree from the Friedrich-Wilhelm University in 1945, Peters began his academic research of synchronoptic world history. This topic was introduced to him during college and formed a large part of his dissertation, titled "Film as a Means of Public Leadership". Though Peters discussed his world map as early as 1967, he did not start promoting it until a press conference in Bonn in May 1973. In 1974 Peters founded the Institute for Universal History in Bremen, Germany where he served as director. He was awarded an honorary professorship by the University of Bremen and worked in Bremen until his death on 2 December 2002.
In childhood Peters lived in Berlin, Germany with his brother, Werner and his parents Lucy and Bruno. The family often entertained foreign guests, and he was exposed to social activism because of his parents' role in the labor union movement. His father was briefly incarcerated by the Nazi regime toward the end of World War II. Peters competed as both a cyclist and a swimmer in high school, receiving titles in both. Returning to Germany after studying film in Hollywood, Peters was able to improve the German production process, and in 1940 he released a film of his own, "Immer Nur Du", a modern musical. At the age of 25 he was the youngest German filmmaker of the time.
In 1945 Peters attained a PhD from Friedrich-Wilhelm University (now Humboldt University of Berlin) in history of art and journalism. Spurred by his interest in political propaganda, he spent much of his academic life studying synchronoptic world history, which focuses on all areas of the world equally. Out of these studies came his "Synchronoptic World History" timeline, devoting the same space to all areas and times of the world simultaneously, spanning 1000 BC to 1952 AD, based on the theory that viewing all civilizations and countries concurrently shows relationships and influences that might not otherwise be obvious. Published in 1952, it presaged his world map. In these activities Peters developed a belief in the Eurocentric bias of most maps. Since he could not find a map that satisfied him, Peters developed one himself. In 1974 he announced the Peters World Map, claiming it was the most accurate representation of the world. The map engendered controversy. The map projection Peters claimed to have developed had been presented more than a century earlier by the Reverend James Gall, and, despite Peters's claims, the projection was not the first or only equal-area projection. Many other of his claims were disputed or debunked. Despite criticism, over 80 million of Peters's maps have been distributed worldwide. In 1989 Peters published "The Peters Atlas of the World", which at the time was the only atlas that represented all areas on about the same scale.
