On this day in 1935 – The world's first parking meter is installed in Oklahoma City, Oklahoma.

Roger W. Babson had filed the first patent for such a device on August 30, 1928. As well as being an entrepreneur, he was an academic who founded three colleges, two of which still exist: Babson College and Webber College, now Webber International University, in Babson Park, Florida.

An opportunist, Babson had 10 Commandments for Investing.

1. Keep speculation and investments separate.

2. Don't be fooled by a name.

3. Be wary of new promotions.

4. Give due consideration to market ability.

5. Don't buy without proper facts.

6. Safeguard purchases through diversification.

7. Don't try to diversify by buying different securities of the same company.

8. Small companies should be carefully scrutinized.

9. Buy adequate security, not super abundance.

10. Choose your dealer and buy outright (don't buy on margin).

Remember those the next time you put money in a parking meter.

I pulled my car into a space.

It was a double seater.

Alas, my claim, I'd soon erase.

There was a marking meter.

I had no coin inside my purse.

No Paul to rob nor Peter.

The news from bad, grew worse and worse.

Unwelcome parking greeter!

I drove away. I'm driving still.

I totter and I teeter.

I can't afford another bill

To pay the parking meter.

Note: It was in 1932, that "Carl Magee began to work on the parking meter and since his parking meter was the first to be installed for actual use on July 1935 in Oklahoma City, Magee is known as the inventor of the parking meter." (Wikipedia)
