Carl was a wonderful mentor, colleague and friend. He had enormous impact on those lucky enough to interact with him directly and on the wider community through his public health contributions. He inspired me and countless others to commit to careers in environmental epidemiology, always with a kind and supportive helping hand gently holding us to high standards. Ever humble, he was a role model for how to be a positive force in this world. Over the decades, we stayed in touch and I always looked forward to his long, hand-written letters full of reflection and wisdom. He will be dearly missed.
