Incorporation and levels of scrutiny

[nicki]

Just curious guys, I know you guys are sharp.

When did the courts come up with so called different levels of scrutiny. I heard this happened in the 1930's. Is this a FDR thing?

When did the SCOTUS start to finally incorporate the Bill of Rights, first cases and how when did they "create selective incorporation".

Thanks for you help

The Wikipedia summary has good answers to your second question.

Scrutiny levels have been developed in the first amendment context along about the same timeline.
