Wow, John! Thank's so much for sharing this amount of detail on the genesis
of the D series of illuminants. I feel dismayed that so little attention was
paid by the original scientists to documenting the time of the day and
seasons of the year when the data was actually recorded, for the benefit of
future generation like us.
One thing that broke my heart as I was reading your account is the reference
to those scarce optical journals. I know the Munsell Lab in Rochester has
copies of everything that was ever published, scientifically, about color
and color metrology. But outside of this lab and a few other places in the
world, one in Japan, one or two in England and a few others scattered in
Europe, no one is seeing the need to reprint or at least publish in some
form some of those original priceless papers and journals for the benefit of
today's generation of color enthusiasts that want to access some of the more
fundamental texts in colorimetry.
Thank you so much for taking the time to contribute your knowledge and
information!
Roger Breton
