Behind every invention is a creative mind, a great idea, and a ton of dedication. From alarm clocks to zippers, inventors throughout history have shaped the world with their creations. Some have changed the way we communicate, others the way we see the world, and many have made daily life just a little easier. Here’s a look at 35 clever creations we still rely on today, and the brilliant minds behind them. Prepare to be surprised at how far back some of these everyday inventions go, with some stretching hundreds of years into the past, proving genius ideas never go out of style.
#1 The Personal Computer: Steve Wozniak
In 1976, Steve Wozniak invented the Apple I, officially kicking off the home computing era. Just a year later, Wozniak designed the Apple II, the first personal computer with color graphics and built-in BASIC programming language. By 1978, the Apple II had become one of the first successful commercially produced computers in the world.

#4 The Alarm Clock: Levi Hutchins
In 1787, Levi Hutchins, an American clockmaker, created the first mechanical alarm clock. He kitted one of his wooden clocks with a gear that tripped a bell every morning at 4 a.m. Because Hutchins didn’t patent his invention, fifty years later, French inventor Antoine Redier patented his own version of the clock, which could be adjusted to go off at other times besides just at 4 a.m.

#5 The Ballpoint Pen: Laszlo Josef Biro
Although the first ballpoint pen was invented by John J. Loud in 1888, László József Bíró patented the first commercially successful one about five decades later. In 1930, he used a combination of newspaper printing ink and a ball-shaped metal nib to create the initial design. By 1938, he had patented a new ballpoint pen that had a tip with a ball rotating in a socket.

#12 Mason Jar: John Landis Mason
John Landis Mason was the inventor of the mason jar, one of the most iconic household products in history. Mason invented the sealable glass containers in 1858 as a way to perfect the art of food preservation, which at the time was quite rudimentary. Sadly, because his patent expired in 1879, from then on, other manufacturers were free to use his designs without compensation.

#13 The Mobile Phone: Martin Cooper
Widely regarded as the “father of cellular phones”, American engineer Martin Cooper built the first mobile phone. Cooper was also the first person ever to make a phone call using one in New York City in 1973. From his prototype, weighing a whopping 2.5 pounds, the Motorola DynaTAC 8000x was born and made available to purchase at the staggering price of $3,995 in 1983.
