If it wasn't for him, who knows if Apple would exist. When you turn on your laptop or desktop PC, you use seven of its patents at once.
It was Lubomyr Romankiw, born in Zhovkva, Lviv region, Ukraine, a leading IBM scientist and electrochemist who invented the thin film magnetic heads for information recording that made hard disks and personal computers possible.
He developed the industrial process, as well as the tools and everything else needed to get hard disk drives into production.
"Apple was founded in the way that Steve Wozniak bought these disks from us and, as he says in one of his posts, built the first personal computer in his garage.", said Lubomyr.
Lubomyr also invented the technology of soldering microcontacts on the computer chip and the technology of forming multi-level connections. Now this technology is used in every computer in the world.
The fact that you read this text on your computer, you owe it to Ukrainian engineer ;)
