We were heartbroken to learn of the passing of Derek Gray. The international liquid crystal community has lost a scientist who made remarkable contributions to the field, particularly in cellulose liquid crystals. Derek's legacy will serve as a guiding light and an inspiration for future generations. Derek received important international recognition for his outstanding work on cellulose, including the prestigious "2013 Marcus Wallenberg Prize". Derek leaves behind a vast legacy for all of us, as well as "saudade" among those who had the privilege of knowing him and sharing his time and knowledge. Derek will be deeply missed.
