Gut-wrenching horror at boy's ordeal.
The former assistant principal, along with former residential social worker Ian Merry, had tried to warn of abuse at the school three decades ago but was ignored.
"I have now seen your article in the Chronicle and I commend both the story itself and the stance taken by your editor," he wrote.
"Had the governors acted upon my advice and Ian's concerns, the abusive 'career' of Brown would have ended many years ago."
The respected teacher also told of his horror at the depravity of Kevin Brown's abuse, which was finally revealed by prosecuting counsel during Brown's sentencing at Newcastle Crown Court.
"I have to say Ian and I were profoundly shocked at the depravity we heard for the first time," he wrote.
"I don't think I have ever felt such gut-wrenching revulsion and I couldn't bring myself to discuss the accounts with my partner for fear of breaking down again.
"How the poor victim endured such abuse God only knows - my heart went out to him.
"I'm very glad you gave Ian credit. He has been astonishingly brave and resilient in pursuing justice."
