Imogen Cunningham went to photo school in Germany, almost 100 years ago. 
  Her thesis (or whatever it was called) concerned substituting lead for 
platinum in a print process.  I guess it worked, but later in life she 
couldn't remember how to do it.  For a lady who would (according to her 
son) use any developer that anyone suggested to her, it seems like it 
must have been somewhat a stretch.  With the price of precious metals 
today, it would be great if someone could reproduce that process now.

Just don't eat the prints.

I recall that platinum photography had an advantage as it was cheaper than
Not from being there.
But from reading about it.

Then it went up. Why I don't know.
Maybe it was because they said "hey this is platinum!"
