10 comments on “Barry Cooper, 1943-2015

  1. I am sincerely shocked: I knew Barry Cooper since 1971 (that makes 44 years), when I met him in Berkeley. I learnt recursion theory from him, in the sense that he was supervisor of a “reading course” I took. My teacher Barry was 28, I was 23. I somehow kept contact with him, mostly his merit. I am sincerely shocked.

  2. I am in shock because of his sudden death. He was a great mathematician and a very good friend, indeed. He will be missed…

  3. Barry and I became close friends and emailed each other daily. We had many interesting conversations on quantum computers and the limit of algorithms, mathematics, wave functions and collapse to metaphysical aspects of the mind and personality….and all of it was always tied to Alan Turing. We talked about codes in music to simply what music we like. We talked a lot about Alan Turing. He shared a number of photos of himself as a child, adolescence, college and present day to me and I shared my photos and artwork to him. We spoke daily for the last 2 years. On 14 October he told me he was ill awaiting test results, then he told me he had abvanced cancer and was given 3-6 months to live. In his last email he told me he wanted to spend the time he had left to his research. His last words to me was ” you and Alan are very important to me”, “we will talk later”. I desperately tried emailing him but never heard back.
    I dearly miss talking to him, my computer is eerily quiet, I dearly miss our lively conversations, he was my best friend, I shall deeply miss him.

  4. Barry was a very good friend. A terrible shock to loose so suddenly. He told me he wasn’t feeling well early in September, we talked almost everyday

  5. I met Professor Barry Cooper many times at CiE and European Logic Colloquiums since 1990, and my colleagues working in pure computation theory told me that Professor Cooper has been one of main contributors in the filed since many years ago. I do very regret, … my condolences …

  6. Barry was the best friend of Bulgarian Logic. We miss him very much and we love him
    a lot. I personaly will miss him deeply.

  7. I knew Barry in the 70s as a fellow comrade in the communist party. Barry always impressed me with the gentle, unassuming manner in which he would apply sound logic and thoughtful analysis to difficult political issues. I regret not having made cont\act again after many years away from Leeds.
