The Harris Tweed Authority said on social media yesterday (Monday January 11).
"On Sunday the 10th of January, we were deeply saddened to learn of the death of our friend and colleague Mr Norman Mackenzie of Carloway Tweeds.
"Norman was a such a good, giving and interesting man – he was a true gentleman.
"Over the years, we must have asked Norman to host hundreds of visitors to our industry in his lovely weaving shed in Carloway.
"He never once complained when we asked him for a favour, and he always gave so willingly and generously of his time and knowledge.
"Having returned to the Harris Tweed industry following his retirement as a dentist, Norman shared passionately to his guests his love of the Harris Tweed industry and was so articulately able to explain its importance to our island culture and economy.
"Always ably supported administratively by his wife Irene, together they became great friends and supporters of the HTA and we are so grateful for that.
"Our most sincere condolences to Irene and the family at this sad time."
