Transcript of 1930 Inventions
•The longest MONOPOLY game in history lasted for 70 straight days
•The most expensive version of the game was produced by celebrated San Francisco jeweler Sidney Mobell. Valued at $2 million, the set fea tures a 23-carat gold board and diamond-studded dice. In 1932 the Polaroid camera was created.
Edwin Land was an inventor who specialized in working with polarized light.
It was an interest he discovered in 1926, during his freshman year at Harvard.
During that year, he temporarily left school to work on creating the Polaroid--a new type of polarizer that involved using crystals inside of a plastic sheet. The prototype trampoline was built by George Nissen, an American circus acrobat and Olympic medalist. He invented the trampoline in his garage in 1936 The US Air Force, and later the Space Agencies, used trampolines to train their pilots and astronauts Richard Drew, a young 3M engineer, invents Scotch® Tape. This tape is an attractive, moisture-proof way for grocers and bakers to seal packages. The tape helps people “make do” during the Great Depression—they made simple repairs to household items. Carlton Cole Magee invented the first parking meter in 1932 in response to the growing problem of parking congestion.
The first was installed in 1935 in Oklahoma City. The meters were sometimes met with resistance from citizen groups; vigilantes from Alabama and Texas attempted to destroy the meters en masse. The inventor of the first ballpoint pen to be successfully put on the market was Laszlo Biro, who made a pen with a pressurized ink cartridge. Biro was a journalist, and he noticed that the ink used for printing newspapers did not smear or run immediately. He used this ink in his pen with a ball bearing in the tip to help the thicker ink flow. Created in 1933 and it was the world's first production model electron microscope.
