Knut was born at Berlin Zoo in December 2006. His mother rejected him. Zookeeper Thomas Dorflein raised him by hand, sleeping beside his crate, feeding him through the night.

Knut the Polar Bear

A polar bear cub born in Berlin was rejected by his mother and kept alive by one zookeeper who refused to give up on him.

December, Berlin

Knut was born on December 5, 2006, in a den at Berlin Zoo. He and his twin brother arrived in the night, small and white and barely formed. Their mother, Tosca, walked away from them. She did not come back.

The twin did not survive. Knut was alone.

The Keeper Who Stayed

A zookeeper named Thomas Dorflein took the cub home. He built a warm space beside his own, set up a feeding schedule that ran around the clock, and started over every two hours through the night. A bottle. A blanket. A voice that was there when the cub woke up.

Polar bear cubs nurse for more than two years in the wild. Dorflein had signed up for something long.

The Bear Who Grew Up Famous

In March 2007, Knut was introduced to the public. The crowds that came to Berlin Zoo that spring broke records. People stood in lines that stretched across the grounds, waiting for a look at the white cub who had lived when he should not have.

Knut appeared on the cover of Vanity Fair beside Leonardo DiCaprio, an unlikely pair who both stood for something the world was trying to figure out how to talk about. Climate change. Polar bears. What was being lost.

The Bond Between Them

Dorflein and Knut had something that did not translate into a simple caption. The keeper wrestled with the bear on the grass. He fed him by hand. He was present in a way that shaped how Knut understood the world, because Knut had no other reference point.

Some critics said it was wrong to raise a bear this way, that it made him too human, too dependent. Dorflein did not argue. He just kept showing up.

The Keeper Who Left First

In September 2008, Thomas Dorflein died. He was forty-four years old. A heart attack, sudden and without warning. Berlin mourned him, and so did the people who had followed Knut from the beginning.

Knut was two years old. He continued to live at the zoo, and people continued to come. But the person who had started his life, the person who had been there before anything else, was gone.

What They Both Came to Mean

Knut died in March 2011, at four years old. A brain condition. He collapsed in his enclosure while visitors watched, and that was the end of it.

Berlin held a public memorial. A statue was cast and placed in the zoo. Knut had been many things: a rescued cub, a media sensation, a symbol. But at the start, before any of that, he had been one cold night and one person who decided not to leave. That is where the story begins and where it keeps returning.
