Two things:-
1) Construction steel.
2) Lifts.
They could loosely be said to have invented skyscrapers as they made use of six or seven storied apartment buildings called "insulae". They could be considered the skyscrapers of their time.They could loosely be said to have invented skyscrapers as they made use of six or seven storied apartment buildings called "insulae".

One technology that made skyscrapers possible would be the elevator. The other, I suspect is structural steel.
STEEL! Elevators Telephones Efficient pumps
strong steel made it possible to build skyscrapers and suspension bridges
The invention of steel skeletons and elevators made building skyscrapers possible
Skyscrapers? Just guessing! Hi Kyle :) That is a wrong answer its underwater homes! WEEYUM! Really you guys! Haha, JHS I'm assuming? Hahahahaha lookin ahhh
The earliest skyscrapers were the result of design breakthroughs and industrial technology in the late-1800s. These tall buildings were made of fire-proofed iron and set on deep foundations.
Electricity powered homes and factories. How did electricity change Americans' lives?
