The director of Gasworks and Triangle Network, Alessio Antoniolli, has announced that Robert Loder, the collector, philanthropist, and cofounder of the Triangle Network—an international consortium of small-scale arts organizations and projects that support and disseminate the work of emerging artists through artist-led workshops, residencies, exhibitions, and outreach events—has died.

Created with artist Anthony Caro in 1982, the Triangle Network started with an artists’ workshop in upstate New York in the summer of the same year and soon expanded its activities to South Africa, where Loder had founded in 1959 the African Arts Trust to support black artists from the country. Starting in 1968, Loder became a trustee and then served a ten-year term as chair of the Mental Health Foundation. He was awarded the title of CBE for his service.

Loder was the treasurer of the Institute of Contemporary Arts in London, and later became its chairman in the 1970s, but he will perhaps be best remembered for founding Gasworks, a nonprofit contemporary visual-arts organization based in London, in 1994. As part of the Triangle Network, Gasworks has collaborated with more than 250 artists from seventy countries, provided studios for London-based artists, commissioned many of the first major exhibitions in the UK for emerging national and international artists, and maintained an international residency program in London.
