Jack was infinitely helpful with the writing of the biography of his father, George R. Stewart. He shared his memories in great detail, and (like his sister Jill Stewart Evenson), brought life into the book.)
Jack once said that it was hard to be the son of George R. Stewart. He felt overpowered by his father’s ability to research and write works that helped define the twentieth century by popularizing the ecological view of human affairs decades before anyone else did so.
The incident which most shows how George R. Stewart felt about Jack is in the great classic, Earth Abides. At the moving conclusion of the novel (which was dedicated to Jill), Ish, the human hero passes his hammer – symbol of power and leadership – to his descendant Jack.
There was a real hammer. Jack inherited it. So, in the real world as well as George R. Stewart’s world-changing book, Jack became the keeper of the Hammer of Ish.
If you are so inclined, and find a moment to do so, please send some positive thoughts toward Jack, and his family.
