454 THE NEW WORLD OF SCIENCE (1946-51)<br />

Capable <strong>of</strong> handling large amounts <strong>of</strong> statistical data with revolution-<br />

ary speed, thoroughness, and efficiency, <strong>the</strong> new machines permitted, among<br />

o<strong>the</strong>r things, <strong>the</strong> solution <strong>of</strong> equations hi<strong>the</strong>rto, from <strong>the</strong> standpoint <strong>of</strong> time,<br />

impossible to solve, and were to take <strong>the</strong> guesswork out <strong>of</strong> problems previously<br />

undertaken by constructing costly experimental equipment, such as <strong>the</strong> wind<br />

tunnels used in aerodynamic studies.<br />

The computer project at <strong>the</strong> <strong>Bureau</strong> was first assigned to <strong>the</strong> machines<br />

development section <strong>of</strong> <strong>the</strong> applied ma<strong>the</strong>matics division. An increasing<br />

amount <strong>of</strong> its component research, however, was carried out by ano<strong>the</strong>r com-<br />

puter section, that under Dr. Chester H. Page and Samuel Alexander in Dr.<br />

Astin's electronics division. in <strong>the</strong> latter division, utilizing its research in<br />

specialized electron tubes, high-speed memory organs, transference means,<br />

input and output equipment (a system <strong>of</strong> electric typewriters and magnetic<br />

recording devices derived from standard teletype machines), and transcribef<br />

and converter elements, <strong>the</strong> first <strong>Bureau</strong> computer was built. A crucial<br />

breakthrough was <strong>the</strong> substitution <strong>of</strong> <strong>the</strong> new germanium crystal diodes <strong>for</strong><br />

electron tubes in all switching and computing elements, with tubes used only<br />

<strong>for</strong> power amplification.77<br />

In 1947, a year after <strong>the</strong> <strong>Bureau</strong> began its research on computer<br />

components, <strong>the</strong> <strong>Bureau</strong> <strong>of</strong> <strong>the</strong> Census and <strong>the</strong> Office <strong>of</strong> Naval Research, with<br />

assistance from <strong>the</strong> Air Force, contracted with <strong>the</strong> <strong>Bureau</strong> <strong>for</strong> <strong>the</strong> construction<br />

<strong>of</strong> two full-scale computers at an estimated cost <strong>of</strong> $300,000 each. Their<br />

design was assigned to <strong>the</strong> Eckert and Mauchly Computer Corp., <strong>the</strong> Ray-<br />

<strong>the</strong>on Manufacturing Co., Massachusetts Institute <strong>of</strong> Technology, and Tufts<br />

College. One was to be assembled in <strong>the</strong> electronics division in Washington,<br />

<strong>the</strong> o<strong>the</strong>r at <strong>the</strong> <strong>Bureau</strong>'s Institute <strong>for</strong> Numerical Analysis, recently organized<br />

at <strong>the</strong> University <strong>of</strong> Cali<strong>for</strong>nia at Los Angeles.78<br />

Presiding over <strong>the</strong> computer project, Dr. Condon saw <strong>the</strong> <strong>Bureau</strong> as<br />

"<strong>the</strong> centralized national computer facility" <strong>for</strong> <strong>the</strong> Government, <strong>the</strong> Wash-<br />

ington unit serving <strong>the</strong> eastern half <strong>of</strong> <strong>the</strong> Nation, that at Los Angeles <strong>the</strong><br />

The germanitim or silicon crystal as transistor, first developed by Bardeen, Brattain,<br />

and Shockley, physicists at <strong>the</strong> Bell Telephone Laboratories, in 1948, conducts electrical<br />

current in much <strong>the</strong> same way as a vacuum tube. Unlike <strong>the</strong> tube, which boils <strong>of</strong>f<br />

electrons flow as directed by an electrical field, <strong>the</strong> transistor operates without<br />

heating and <strong>the</strong>re is nothing to burn out (Bernstein, The Analytical Engine, p. 68).<br />
