R.I.P. Knut: Remembering the famous Berlin Zoo polar bear's life in photos
Knut, the polar bear whose famously cute visage landed him a Vanity Fair cover and earned him legions of fans back when he was a cub in 2006 and 2007, died over the weekend of unknown causes. The celebrity bear, who was 4, died in his outdoor enclosure at the Berlin Zoo.
Zoo staffers are anxious to determine the cause of Knut's early death, considered extremely unusual for a species that can live up to 20 years in the wild and even longer in captivity. Knut had not appeared sick before his death and he was visible to 600 or 700 people gathered around the zoo's polar bear enclosure at the time of his death on Saturday.
Although it's hard to believe this beloved bear -- frozen in so many fans' memories as an energetic, full-of-life cub -- is gone, we had to smile when looking back over some of his earliest photos. Beginning in early 2007, not long after his birth, they showcase his first months in the spotlight and the special relationship he shared with his late keeper, Thomas Doerflein, who died in 2008.
We've assembled some of our favorite photos of Knut, ranging from his first year all the way to his fourth birthday last December, concluding with images of the makeshift memorial that sprang up at the Berlin Zoo over the weekend as Knut's many fans arrived to pay their respects. (For fans who live a long way from Berlin, the zoo has also set up an online memorial book for Knut.)

RIP Knut, you always made me laugh & brightened my day, silly, charming, and all Polar Bear <3

This is so sad. I read somewhere that he wasn't accepted, and the other Polar Bears abused him. That PETA tried to get the zookeepers to protect him but they hadn't yet. I hope that isn't true. How sad for the little children to have seen that. RIP Knut.

He's a wonderful creature, please go to Berliner Zoo website to write something to him. It's important to let the zoo understand people around the world love this special bear. Thanks.

Precious Knut introduced me to the world of magnificent yet charismatically endearing bears. He brought so much joy into my life and the lives of countless thousands of people all over the world. We were all blessed to have his sweetness and goodness with us, even for too short a time. Sleep now sweet angel. I will always love you and cherish your precious memory.

Pretty sad.

The other polar bears did not, I repeat did not, abuse Knut. They wanted to play with him, - he's the one who didn't accept them. Until about a year ago, he had never seen another polar bear, so he was afraid of them. The first one he accepted was Tosca, they played together in the water and had lots of fun. In the last month or so, he accepted Nancy and they exchanged kissies. The one polar bear that he hadn't accepted yet was Kati, who was too assertive for the gentle bear. I have seen hundreds, maybe thousands, of photos and videos of the 3 ladies being curious about him, and he would ROAR them away. The zoo keepers loved Knuti very much and would never have allowed him to be abused or attacked.

Knut is at Rainbow Bridge where all loving animals go. What an absolutely precious bear. God blessed us with him for a short time but what he did with his short time on earth. Be happy in Heaven beautiful baby.

This bear has touched my life for the last 4 years. Every day I would check in on him. I made friends all over the world, fellow fans, that I still keep in touch with. He represented something so powerful, so magical, so innocent, charming and mysterious. His life and death now seems elevated to that of many of died young and are still remembered intensely. He is an icon. What is it about him, a bear??? I cannot fathom but his grip on me is undeniable.

it would have to happen in germany - they will never get over it. sure he was a great little tyke but the germans will take it to heart too much. anything not associated with the green party will take some blame as well. the little guy will wind up being the metaphor for the "99 luftballons" of a new generation, but . . . would the bear have wanted it that way? memorials are for the living indeed.

Knut made us pause and reflect on the beauty of the animal world.

I saw the video. He looked very distraught. It is a tragedy when a captive creature gives up like that.
He was conditioned to being with the loving hands of a human trainer. Not with the brutality of bears. It may have ultimately done him in.
Way to go experts. When I pass soon, I hope you look at your own filthy hands the same way a zookeeper does.
Scum.

Certainly, this adorable polar bear will be missed.

I remember the little guy from 2006. There were some really cute pics of him....like these. So sorry to hear things didn't turn out well for him.
Peace, Ours blanc
