Harrison Brown

They were kind of horrified at what their work had wrought.

And so his advisor, Harrison Brown, who was a pretty famous scientist in his own right, he said, well, why don't you figure out the age of the Earth? You're really good with the mass spectrometer.

We've got better equipment now.

We've got these meteorite samples.

So I call him Dave, like to think of him as sort of a friend after writing all this stuff.

Dave Keeling, he loved to go camping and he actually worked as a postdoc at Caltech in the exact same lab that Patterson worked in.

So Harrison Brown was the advisor and Keeling got his start grinding up granite, which I am almost positive was actually used for Patterson's research.

So there's like another connection there.
