  1. Texas Instruments ✔
  2. Intel
  3. IBM

Why: On 12 September 1958, Kilby showed TI managers an oscillator circuit built on one small germanium bar. It earned him the 2000 Nobel Prize in Physics.

Huh, didn't know that: Robert Noyce at Fairchild separately developed a silicon IC soon after, which became the way chips are made.

The dad joke
Kilby put a whole circuit on one chip. Talk about integration skills.
