The Nuclear Bomb Effects Computer Versions 1, 2 & 3

There were three versions of the Nuclear Bomb Effects Computer.  The first was designed by EG&G.

“EG&G, formally known as Edgerton, Münchhausen, and Grier, Inc., was a United States national defense contractor and provider of management and technical services. The company was involved in contracting services to the United States government during World War II and conducted weapons research and development after the war.” Wikipedia.

The calculator was based on test data published in the first edition of the ‘The Effects of Nuclear Weapons’.  The calculator is made of plastic and is 4″ in diameter. A complete set consists of the calculator, a red and white sleeve and an instruction pamphlet.  This cold war calculator is very rare.

The third version of the calculator was also designed by the Lovelace Foundation. Its design is much improved over the earlier versions and is based on a revised test data set which was published in the second edition of the ‘The Effects of Nuclear Weapons’. The calculator is 5″ in diameter and is made of plastic. This version is not rare. Copies of the calculator were on public sale for $1 along with the revised edition of the ‘The Effects of Nuclear Weapons’ for $3.  The calculator was used as a prop in the Dr Strangelove film and copies were given away to promote the film.
