I am glad Turing is getting the recognition he deserves, but I am always a bit saddened that in the discussions more isn't made of Tommy Flowers who, although working under the direction of Turing and Max Newman designed and built Colossus - and personally financed it.

Things would have taken a great deal longer if the guys at Bletchley hadn't had the expertise of Flowers to turn their maths theorems into mechanical reality.

They are all giants in their field and should all be recognised.
