BUSH, Vannevar:
As we may think. Atlantic, 1945, 176, p101-108

Bush, considered one of the fathers of the computer age, discribes the "memex",
a future device for the storage and retrieval of information. He was among the
very few who in 1945 understood that the computers are not just calculating devices.
He writes that the memex is "a device in which an individual stores all his books,
records, and communications, and which is mechanized so that it may be consulted
with exceeding speed and flexibility" (p106 in text).

The ENIAC. Electrical Engineering, 1948, 67, p163-172.

The construction of ENIAC (Electronic Numerical Integrator and Computer) was
finished by late 1945. It was operational until 1955. ENIAC weighed 30 tones,
contained 18,000 vacuum tubes, and draw 150,000 watts of power; could perform
approximately 5000 additions, 357 multiplications, or 38 divisions per second. It was
the first electronic general-purpose automatic computer, and was a landmark leading
to the development of many automatic computer designs.

WILKES, Maurice Vincent:
The EDSAC, an electronic calculating machine.
Journal Scientific Instrum.. 1949, 26, p385-391.

During his first visit toAmerica in 1946 Wilkes saw the ENIAC at the Univ. of
Pennsylvana, and met American pioneers in computer science. On his way back to
England he conceived the EDSAC (Electronic Delay Storage Automatic Calculator).
It was built at Cambridge University and became operational in 1949. It was the
world's full-scale computer that performed electronic binary computations while
storing its program and data in the same memory. The programs needed to
operate the machine were actually built into the machine itself rather than having
to be fed into it.
