Who invented ET

[A440A@AOL.COM]

Greetings, 
   Not really intending to nit-pic-ric, but I got a few questions: 

<<There are mentions that the Chinese knew the concept 3000 years ago> 

   I have nothing to do but agree with that, (just because I've been told 
this often....)

>>Aristoxenes gave the math concept in 400 BC (ca)<<

   It was my understanding that Aristoxenes promotoed a 12 notes scale 
consisting of 10 equal steps and two larger ones.  If this is correct, I 
don't think we should consider Aris to have been promoting what we are 
pointing to as ET>>

<Vicenzo Galilei in 1581 for ET on the lute. (18/17 ratio)>
  Yes,  dang close to ET, but did he not admit to the slight compromise? 

<<Mersenne gives very close monochord lengths for ET in 1635.> 
   I read Jorgensen to state that Mersenne gave the definitive mathematical 
ratios for ET.  
 
<<James Broadwood writes how to tune it in 1811.>> 
    I was not aware that Broadwood wrote "how" to tune it, just that his 
factory was then using "ET",( but Hipkins and Ellis seem to offer a different 
point of view>
 
<<Claude Montal tuning instructions of 1837>>
    Were not the Montal writings published in 1832?  (Not sure on this one 
either)
Dang, the coffee cup is empty, it is 5:30,  and I gotta go begin a four 
piano, one pinblock day, 
Regards all,
