Sorry, I misunderstood that previous post, I did not read it properly.

According to Moore (1681) the lens "... was the contrivance of Ingenious 
Mr. Flamsteed". Perkins (1682, published posthumously) too seems to 
mention Flamsteed as the inventor (I have not yet read this book, but it 
is mentioned by both Waters and Cotter). May (1973) confirms this, but 
wrote that "... it was not universally accepted..." (Flamsteed being the 
inventor). Other modern authors like Waters (1958), Cotter (1983), 
Warner (1988) and M�rzer Bruyns (1994) contribute the invention to 
Flamsteed without hesitation. M�rzer Bruyns (2003) tells us that since 
1662 Hooke was 'curator of experiments' of the Royal Society. Hooke is 
of course known for his single reflecting instrument, which he presented 
in 1666.

Now if you say that Hooke invented the Flamsteed lens then I guess that 
shares you among those that make it not universally accepted and it 
makes me very curious as well. Could you please explain where we can 
base this on? Is it because Hooke was curator of experiments or was it 
actually mentioned somewhere? When the Philosophical Transactions became 
available on-line earlier this year I tried to find more information on 
the Flamsteed lens. Flamsteed did publish a whole lot around the period 
the lens was introduced, but nothing about the lens itself (or I did not 
find it). I always found it strange that there was no such publication 
by Flamsteed which could be explained when Hooke did invent the lens.
