CONLANG timeline

Hi!

I'm working on a conlang timeline for an exhibition at my university. Up to
now the only conlangs on the list are auxlangs and loglans. I think it
needs some true artlangs, so I would like to ask you if you sent me your
(sur-)name, the name of your artlang and the year of "publication", e.g.

Sommerfeld, Lhuvan, 1993
Sommerfeld, Hfarakhi, 1996

    or

Sudre, Solresol, 1866
Zamenhof, Esperanto, 1887

or something like that. You would be of great help...

Thank you in advance

Regards

--Sven Sommerfeld
