[ATM] Is it correct?

["Ukyo Chen" <ukyochen888@hotmail.com>]

Hi all,

I recently hear that Robert Lurie had made the first Lurie Houghton 
telescope in 1979(sorry I forgot the information source), In this situation 
we can call a telescope with 2 sphere lens correctors, 1 sphere mirror and 1 
diagonal mirror as a 'Lurie Houghton' system. Like this:

Does anybody know it is correct or not? Who had made the first telescope of 
this type in the world?
I had searched in Google for quite a while but only Houghton's theory can be 
found, no result for the first maker.

Thanks in advance!

Best Regards,
Ukyo Chen
