Radio/TV Transmission
Ernst Alexanderson invented the radio/TV transmission in 1920. Before his discovery, radio transmission consisted of a series of dots and dashes that were transmitted by inefficient machines. After rigorous experiments and tests, he came up with a high-frequency alternator that caused radio waves to become successful. A few years later, he developed a scanning disk and a high frequency neon lamp for television transmission.
The Band-Aid
Earle Dickson came up with the idea of the band-aid to assist his wife who cut herself often while doing household chores. Because he worked at Johnson & Johnson, he used a piece of gauze and tape from that company. He told his boss, James Wood Johnson, and he decided to put the band-aid into production. In 1924 it went into mass production and Earle Dickson became vice-president of the company.
Penicillin
The antibiotic was invented after Sr. Alexander Fleming after studying bacteria. Because penicillin was not approved by the FDA at this time, it was not popular in these times. This invention began to be used widely and to save lives post- World War II.
The Pop-Up Toaster
Charles Perkins Strite invented the pop up toaster in 1919 and patented it in 1920. This toaster was a big improvement from the semi-automatic toaster previously used, as it was able to eject the slice of toast when it was done. The Waters-Genter Company worked on this invention and they developed the first consumer toaster- The Toastmaster- in 1926. It was able to toast both sides of the bread and turn itself off when it was done toasting.
Refrigeration, air conditioning, and home dishwashers made life easier at home. (Sandhyarani). Women also started to have changing social conventions (they started to wear shorter skirts, drink, and smoke).
