Which former US president was nicknamed "Teddy" after he refused to shoot a defenseless black bear?

The answer is Theodore Roosevelt. He earned the nickname "Teddy" after a popular incident involving a hunting trip in 1902. During the trip, Roosevelt refused to shoot a defenseless black bear that had been captured and tied to a tree by his hunting companions. This act of compassion and refusal to kill the bear led to a widely circulated political cartoon that eventually inspired the creation of the Teddy Bear, a beloved stuffed toy named in his honor.
