Soviet think-tanks aside, most probably International Business machines, better known as IBM or Big Blue. Remington Rand Univac another contender, Both were familiar with more orthodox business machines such as typewriters to whichwe should be thankful they retained the asdfjkl; keyboard.
ENIAC was the first digital general purpose computer, built in 1946, and with 17,468 vacuum tubes. The Illiac I, the first computer built and owned by a US educational institution, had 2800 vacuum tubes. The IBM 604 had about 2000 vacuum tubes.
vacuum tubes are the switching components in the first generation computers to process data. later they were replaced by transistors.
The prototype for the Atanasoff-Berry computer was demonstrated in October 1939, it used 11 vacuum tubes. The full Atanasoff-Berry computer (the first electronic digital computer) was finished in early 1942, it used 280 vacuum tubes, 31 thyratrons, and was about the size of a desk.
The ENIAC has 17,468 vacuum tubes. These tubes were the first technology that made computers function. Modern computers do not use this technology.
No, he had to use mechanical gears, etc. because they were the only device technology available in his time. Electric relays were first developed about 15 years after he designed his computer, while vacuum tubes were first developed about 90 years after he designed his computer.

Vacuum tubes.
ENIAC
Oh yes - and for several generations after that. ENIAC, the first mainframe computer, had to be kept in a room with very heavy air conditioning (about 60 degrees) because of the heat generated by all the vacuum tubes.
It used 5200 vacuum tubes.

Mostly vacuum tubes, in place of today's more modern transistors.
