As an adult, Alan Turing proved to be a genius. Among other accomplishments, he was a pioneer in computer science. But when he was a teenager, Turing was less impressive. Here’s what his English instructor said about his work:
Without being lazy, he seems to do his work rather perfunctorily. I should like to see rather more life in him.
And his math teacher:
Works well. He is still very untidy. He must try to improve in this respect.
And his science teacher:
He is keen & has a natural bent for science, but his work is badly spoilt by extreme untidiness.
One headmaster wrote about his integration into the school community:
His ways sometimes tempt persecution: though I don’t think he is unhappy. Undeniably he is not a ‘normal’ boy: not the worse for that, but probably less happy.
