Giant Brains

Edmund Berkeley's Giant Brains was one of the first popular books explaining electronic computers to a general audience, presenting machines as 'giant brains' and describing how they functioned and might be used.

Berkeley, trained as a mathematician and working as an actuary, drew on wartime computing experience to make the subject accessible, selling multiple editions.

The book blended technical explanation with chapters on likely social and moral consequences, anticipating debates about automation and military uses.

Its use of the brain metaphor influenced later thinking about machines and intelligence, contributing to early public discourse on what computers could become.

As noted by McCray, it helped seed interest in computing among non-specialists in the postwar era.
