Here is a list of stuff that was invented in the 1930’s. All of these things are still in use today except for maybe the View Master; I don’t shop for kids toys much so not sure. Also, I don’t know is if these people were the ones who were able to make any money with there inventions during the 1930’s. Was the economy so bad that they had to wait until better times hit to make some money?

Interesting side note on LSD, (Lysergic Acid Diethylamide)It was tested for "curative" properties ranging anywhere from cancer to migraines. There has been no official endorsement one way or another regarding use. Another interesting side note, studies done in the 50s showed a 50% improvement in treating recovering Alcoholics with LSD than AA meetings. However again in 98 a study showed those findings to be inconclusive.
