In 'Revival', what is the name of the minister who experiments with electricity?

In Stephen King’s Revival, the minister who experiments with electricity is Charles Jacobs.

Jacobs is a Methodist minister who arrives in Harlow, Maine, where he befriends the young Jamie Morton. His fascination with electricity becomes clear when he uses a low-voltage device to restore Jamie’s brother Con’s damaged speech after a skiing accident. The apparent success makes electricity central to Jacobs’s understanding of healing.

After his wife and son die in a car accident, Jacobs loses his faith and leaves the ministry. He later reinvents himself as a traveling faith healer, using increasingly powerful electrical experiments to treat illness and injury. His work brings temporary cures, but many patients suffer disturbing psychological effects afterward.

The novel eventually reveals that Jacobs’s experiments are part of a larger attempt to discover what lies beyond death. Readers sometimes remember Jacobs only as a preacher or faith healer, but his defining role is the electrically obsessed minister whose experiments drive the story toward cosmic horror. Revival was published by Scribner in 2014 and draws inspiration from Frankenstein and Arthur Machen’s The Great God Pan.
