Computer books your great grandfather might have read

I have been reading two very different computer books written for a general readership: Giant Brains or Machines that Think, published in 1949 (with a retrospective chapter added in 1961) and LET ERMA DO IT, published in 1956.

‘Giant Brains’ by Edmund Berkeley, was very popular in its day.

Berkeley marvels at a computer performing 5,000 additions per second; performing all the calculations in a week that previously required 500 human computers (i.e., people using mechanical adding machines) working 40 hours per week. His mind staggers at the “calculating circuits being developed” that can perform 100,00 additions a second; “A mechanical brain that can do 10,000 additions a second can very easily finish almost all its work at once.”

The chapter discussing the future, “Machines that think, and what they might do for men”, sees Berkeley struggling for non-mathematical applications; a common problem with all new inventions. Automatic translator and automatic stenographer (typist who transcribe dictation) are listed. There is also a chapter on social control, which is just as applicable today.

This was the first widely read book to promote Shannon‘s idea of using the algebra invented by George Boole to analyze switching circuits symbolically (THE 1940 Masters thesis).

The ‘ERMA’ book paints a very rosy picture of the future with computer automation removing the drudgery that so many jobs require; it is so upbeat. A year later the USSR launched Sputnik and things suddenly looked a lot less rosy.
