Robert Ettinger was a teacher of math and physics.

He is often called the father of cryonics. Cryonics is the way people try to preserve bodies by freezing them. He had this big idea after reading science fiction stories. One story was about a man frozen in space. That man was later brought back to life by robots. Ettinger thought science could do something similar for humans.

He believed that death might be a process we could reverse. He thought future doctors could fix the damage from freezing. In 1962, he wrote a book called The Prospect of Immortality. This book helped start the cryonics movement. It was even read by the famous writer Isaac Asimov.

Ettinger started the Cryonics Institute to help his cause. He also froze his own body after he died in 2011. He hoped that better medicine would wake him up one day. His wife, Mae, was also part of this work. She helped edit his books and ran a magazine for the group.
