The black-furred bear, a female named Winnipeg, was smuggled in Britain during the First World War by Canadian lieutenant, Harry Colebourn.
After the soldier was sent to fight in France, the bear cub was given to London Zoo, where it was watched and loved by AA Milne's son, the real-life Christopher Robin.
To coincide with the beloved bear's special date, Guinness World Records recently caught up with Deb Hoffman, the current record holder for the Largest collection of Winnie the Pooh memorabilia, with 13,213 items.
Deb recently shared her experiences with staff at GWR HQ in London
On being the world record holder, Deb said: "It's so amazing, because everybody knows Guinness World Records and that always makes me feel so honoured to almost be like a Winnie the Pooh ambassador."
