ABSTRACT:

In the early days of digital computing (1929-1949), the computation of an inventory of primes was often used as a take a look at or demonstration drawback. The thought to use electronic machinery to provide a list of primes originated with Derrick H. Lehmer, but it had been later taken up by Claude E. Shannon and recurred as computations on the ENIAC and EDSAC. The historical sequence of computing prime numbers is marked by a turn from dedicated hardware to writing and debugging software, although special-purpose sieve machinery was still designed and used once 1949.
