[Nick Senker]

A great photo of willemite, the mineral used to make eye tubes fluoresce can be seen at 
http://franklin-sterlinghill.com/franklinminerals/index.shtml This is where Alan B DuMont obtained the mineral for his development of eye tubes in 1930 (see http://home.pacbell.net/philbert/tuning_eye/tun_eye.htm click on 'construction' and 'history' ).
