Dear fellow members of the Garrod Association - dear colleagues, dear friends,It is with a heavy heart that I pass on to you this sad news, and share the tribute below which was written by two of his longstanding colleagues and friends in the U.S. Charles was known as 'the father of biochemical genetics in Canada' and he was a founding member of the Garrod Association. Many of us were privileged to know him personally and to receive his teaching, mentorship, inspiration and encouragement. All of us in the field of inborn errors of metabolism across Canada have benefitted immensely from his legacy. We will miss him deeply. Paula
