THE
NEEDLEMAN
AWARD

SCIENTIST - ADVOCATE AWARD for PROTECTING CHILDREN from TOXIC CHEMICALS

The Sanctuary hall of Arantzazu is the centerpiece of a site that has been destroyed and rebuilt many times since its 15th-century origins. The current hall—completed in the 1950s after earlier sanctuaries were lost to fire and war—embodies a bold modernist vision: soaring stone walls, sculptural forms, and a dramatic interplay of light shaped by artists like Oteiza, Chillida, and Muñoz. At once austere and expressive, it stands as a testament to the Basque spirit of renewal and devotion.

Children are essential to our future and the continuation of human life. Children around the world are confronted by multiple environmental threats to health, including toxins, air pollution, psychosocial stress, and climate change. Infants and children are often exquisitely vulnerable to these threats; exposures during critical windows of vulnerability have been associated with a wide range of childhood diseases. Early life exposures can also increase the risk of chronic diseases in adulthood.
