Magnum is a community of thought, a shared human quality, a curiosity about what is going on in the world, a respect for what is going on and a desire to transcribe it visually, said one of the famous photographers on the world Henri Cartier-Bresson.

World Press Photo is run as an independent, non-profit organization with its office in Amsterdam, the Netherlands, where World Press Photo was founded in 1955.

The organization is controlled both by an independent executive board and a supervisory board, and employs around 25 permanent staff. The Amsterdam office acts as the hub for a network of professional contacts worldwide - it is this network that makes organizing the contest, exhibitions and other activities on such a large scale possible.
