>>> I am also familiar with the History of Poser, from its inception in 1994 by a Person named "Larry Weinberg" right up to the present day. I am also aware that DAZ was originally called "Zygone" and created Figures and General Products for Poser. To the Best of my knowledge, DAZ Studio must have been released in 2005 or 2006, specifically because Poser was once again up for sale, and at that time, it was unclear whether the Software would continue to be developed. 

Yes I stand corrected on the release date I posted .... 2005 is correct.

>>> I would still really like to get some answers to the Questions I posed above. Ideally from the Person I mentioned (RHaseltine), it would simply be interesting to know whether this individual is closely affiliated with DAZ and whether he holds a significant Position within the Company. Is he perhaps even part of DAZ’s Senior Management?

I believe he's "official" at DAZ but not sure whether or not he's an actual employee. He's been answering and service as customer service rep for ages. 

You can get a lot of information on both DAZ and Poser on Wikipedia. Search for DAZ Studio, or for Poser. There is a whole boatload of history there.
