He has received countless international awards and honors, both in his professional field of advertising and communication, and in the field that is his greatest passion: presenting photo art in exhibitions and especially in books. Books, he freely admits, occupy a central place in his imagination; he describes himself as a “book junkie”. As a designer, graphic artist and gallerist, he has always put his contacts and talents to work for artists, and he takes pains to remain true to their intentions. Above all, it is a question of identifying the right design. The spectacular 1998 Under/Exposed exhibition, which brought together work by 250 photographers from around the world in the Stockholm metro, is typical of his approach, in the way that it brought together his multifaceted activities. Every photographer – from stars like Sophie Calle and Robert Frank to talented young unknowns – was given four or five 4x3 metre advertising spaces, where a photograph was displayed without the artist’s name and without a title, date or description. It was a startling effort, implemented with close attention to detail, with a true, brave, generous intention to share. It showed how, for Greger Ulf Nilson, design is above all a question of creating meaning. He never seeks to take the place of the artists, but rather to make their work accessible and understandable.
