The history is full of stories about the great inventions of man-kind. These are the inventions that now make our life easier as well as convenient. But some of these came into existence accidentally. Despite that they made a huge change in fields of science and also our life-style. Below is six- great inventions that were accidentally invented.


Saccharin-Artificial sweetener

 Constantin Fahlberg, a Russian chemist, was working in his lab right after which he went to have sandwiches without washing his hands. He realized that the usual sandwich is sweeter. Upon realizing that he discovered that his hand was covered with the compound, benzoic sulfinide, formed after reaction of o-sulfobenzoic acid with phosphorus chloride and ammonia is the one he tasted. Under different circumstances this could have been a health hazard, but luckily he invented something edible.

Pace maker

Wilson Greatbatch, a professor of engineering at the University of Buffalo, in the year of 1956 accidentally invented the pacemaker. He was working on building a device that would record the heart beats and ended up finding the device is giving off electric pulses, similar to that of a heartbeat. Later Greatbatch then introduced his invention to a surgeon, William Chardack, with whom he was to successfully abled control a dog’s heartbeat. And after few years, in 1960, it was able to work on humans too.


One of the man-kinds best invention, Penicillin was invented on accident. In the year of 1928, DR. Alexander Fleming left out his culture Staphylococcus aureus in his lab two week. He was about to throw it away before finding that its growth had being prevented by the mold called Penicillium notatum. From there he isolated the mold and ran tests to determine that penicillin has antibacterial effect on staphylococci and other gram-positive pathogens.


The monks of the champagne, having the best access to grapes, decided to make white wine. Since it was cold it hindered the fermentation process and when the spring came, wine containers were filled with carbon dioxide. The excess of carbon dioxide caused carbonation in the drink. To fix this, French monk named Dom Pierre Perigon came over to champagne handle it. But later people decide that the carbonation made the drink fizzy and hence tastier.



When Frank Epperson was 11-years old, he mixed some soda power with water and left it in the freezer overnight completely by accident. The next day he decided to lick the frozen soda solution and was delighted by its taste. The young boy originally named it as ‘epsicle’, combining icicles and his name, but later he changed it into what we know it as popsicles.


Harry Coover, in the year of 1942, was searching for a material that he could use to build clear plastic gun sights for the war, but ended up with a chemical substance that would stick to everything it made contact with. Despite that, his invention was rejected since the researcher didn’t find any use of the sticky substance. Later in the 1951, the formulation was innovated by Cooper and Fred Joyner as ‘alcohol-catalyzed Cyanoacrylate Adhesive compositions’ or as we know superglue. And from the on the superglue was embraced as one of the most useful invention.
