The 30 Second Mystery 4 - Who?
 

There are four categories: Who, What, Where and Why. Some will be easy, some not. I have as many as six clues to help you along, which I'll supply as needed.

Please limit yourself to one guess, and another guess for each clue I supply. No questions allowed. Partially correct answers won't be acknowledged. Let's see how this goes.

The Case:
A person has the same job for years. The person enjoys his work, but spends most days staring at the ceiling. Despite this behavior, his work turns out to be among the most important ever done in his field.

The Mystery:
Who is the person and what did he do?

Michaelangelo and he painted the Sistene Chapel

You guys are pretty smart. :-)
