Hi Jim,

It was before the lab fire, probably what caused it.  Found it.  Cheney, lab
fire, Mar 13, 1895.  Say's Tesla was working on a way to produce LOX
comercially, work destroyed in the lab fire.  Two of the patents filed after
CS (1900) described gaseous cooling of underground conductors with liquid
air.

What is the date of Linde first doing it?
