HARRY COOVER, the inventor of Super Glue, has died aged 94.

I have super-glued many things including, accidentally, the dog’s ear to his collar.

Mr Coover was awarded the National Medal of Technology and Innovation in 2010 by President Obama.

Everyone who has ever used Super Glue has good reason to be thankful to Mr Coover’s invention.

L Wise, Hartlepool.
