The invention that has had the most benefit to the most people of all time is nothing new. It increased the length and quality of lives and reduced disease.
It is the sewer. The covered sewer is in close 2nd place.
I'm not kidding. Before the sewer, garbage was dumped in the streets where it would attract rats and insects. Rain water ran from these garbage piles into the streets; you could not avoid walking in it and then walking into your home. Vermin were attracted to the filth and spread disease.
It may seem humble and disgusting but the sewer is the greatest invention, requiring the greatest of genius. Remember, this was before the role of germs and vermin had in plague and disease.
Of course, I would hate to be without underwear. :-)

The lever and the incline plane. These items are used in practically every different type of machine around today and provide the most basic ways of gaining a mechanical advantage to transmit force.
Other than that, the transistor. it provides the basic building block of all our current electronics technology, from a stereo amplifier to a microprocessor.
