Answer:

The CDC 6600 from Control Data Corp., is generally recognized as the first supercomputer, according to Wikipedia. Built in 1964, it was designed by Seymour Cray, and ran at about 1 megaflop (a million floating point operations per second). That was about three times faster than the previous fastest computer, the IBM 7030 Stretch. (Today, an iPhone 3Gs can run at about 6.42 megaflops.)

The UNIVAC, which first appeared in 1951, was the first commercial computer produced in the United States.

Seymour Cray left CDC in 1972 to start his own company. The first Cray-1 supercomputer was installed at Los Alamos National Laboratory in 1972.
