when was rudolph the red-nosed reindeer born

Rudolph the Red-Nosed Reindeer was born on Christmas Eve, just like all the other reindeer. However, his red nose was a genetic mutation that caused him to be different from the rest of the herd. The other reindeer teased and bullied him because of his bright nose, and he was even excluded from the reindeer games. But one day, when Santa's sleigh was stuck in a snowstorm, Rudolph's bright nose was able to guide the sleigh out of the storm, and he became a hero to all the children of the world.
