Cheerio Norris... your knowledge of all things factual had me hanging on your every word. The cruel wind snuffs out the candlelight of childhood hero...

Whilst I strongly disagreed with his politics, I admired his enthusiasm for statistics and world records and admired him for the way he managed to carry on after his twin brother's murder

I had the privilege of working with Norris McWhirter on a number of legal cases in the 1970s and 80s. As well as having a needle sharp brain and a legendary memory for facts and figures he was also a very kind and courteous man who was not afraid to stand up for what he believed in.

I was sad to hear of Norris' death. My family had lunch with him when I was about 11 and I remember him treating me like an adult and being more than happy to sign my copy of the Guinness Book of Records as though he did not get asked this all the time. A true gentleman.

For someone with such a passion for politics it is strange that all he is remembered for is The Record Breakers.
James Wild, London, UK
I might not have agreed with his political views but the man achieved a lot during his lifetime and I pay tribute to that.

Definitely a favourite face from the days of my childhood in the 1970s. To my generation he was the grandfatherly, boffin-type figure who was rarely, if ever, stumped when asked about world records, although as an adult I came to appreciate him anew for his political activities. A sad loss, but a good innings for a man who has left behind such warm and fond memories.
Steve Payne, Leicester, UK
I will always remember that Norris McWhirter held the world record for knowing more world records than anyone else! He always exuded an air of authority and somehow you always knew he was right!
Chris S, London, UK
A sad loss. As a child and a fan of Record Breakers I only remember him being stumped once on a question asked by a young boy. If I recall correctly it was about which tree had the most leaves? Rest in Peace!

Fascinated by this man from an early age, I ever wondered if we might be related. Unfortunately, we are not, but I still feel that a part of me, and my childhood years of watching Norris on Record Breakers with the trumpet touting Roy Castle, has been taken away.
David McWhirter, Abergavenny, UK
Record Breakers was a true gem of children's programming, both entertaining and informative. Norris's rendition of the most obscure facts was something I held in awe as a child. Wherever he has gone, I'm sure Roy will be getting his trumpet out for a madcap welcome.

For his death to occur so close to the 50th anniversary of Roger Bannister's first sub-4 minute mile, where Norris announced it as a new world record, is exceptionally saddening. He was a true legend of children's television of the 70s and 80s with Roy Castle on Record Breakers. He'll be missed by a lot of people of my generation.
Very fond memories of watching Norris on Record Breakers all those years ago. A very sad day indeed. Rest in peace Norris.
He will be sorely missed. I will always remember him as the voice of sanity, a granddad figure if you like, over the zaniness and craziness of presenter, Roy Castle. I hope that they are enjoying plenty of Guinness together in the great BBC Green Room in the sky!
CJ, Brighton, England
I always enjoyed all the little titbits of information I learned from the Guinness books; very entertaining material. Norris will certainly be missed by family and fans alike.
Ryan, New Orleans, USA
I am deeply saddened. A wonderful man, of great intellect and spirit. Courageous and warm hearted. I grew up with Norris on my TV each week, and he's a fondly remembered part of my childhood. Now I live far away, the fact that he has died makes me miss home and my wonderful country. God bless, Norris, and sleep well.
Beck, Huntsville, Alabama
I remember first seeing Norris and Ross on Record Breakers, along with Roy Castle and was always carried along with their enthusiasm. Another of my childhood heroes departs this world. Best wishes to his family
Linda, Yeovil, UK
I was so terribly saddened to hear of the death of Norris McWhirter. Along with Roy Castle and Cheryl Baker, he was an integral part of my early years.
Paul Kilby, Glasgow
I was very sorry to hear that Mr McWhirter has passed away. I met him as a 7 year old when my uncle appeared on the show balancing milk crates on his head. He was a complete gentleman and although it didn't always come across on TV, he had a riotous sense of humour.
Kevin Rush, Glasgow, Scotland
His memory was amazing; I can only remember him being stumped once on Record Breakers, admittedly by a fairly daft question "Which tree had the record amount of leaves on it". He, Johnny Morris, Johnny Ball and Roy Castle had a rare quality of enthusiasm which took the dull and informative into something which could entertain bored kids like me in the 1970s. Rest in peace Norris.
