THE EDITORS: DAVID L. BLOCK AND KENNETH C. FREEMAN (SOC CO-CHAIRS),
IVANIO PUERARI, ROBERT GROESS AND LIZ K. BLOCK 1. Harvard College
Observatory, 1958 The past century has truly brought about an
explosive period of growth and discovery for the physical sciences
as a whole, and for astronomy in particular. Galaxy morphology has
reached a renaissance . . The year: 1958. The date: October 1. The
venue: Harvard College Observatory. The lecturer: Walter Baade.
With amazing foresight, Baade penned these words: "Young stars,
supergiants and so on, make a terrific splash - lots of light. The
total mass of these can be very small compared to the total mass of
the system". Dr Layzer then asked the key question: " . . . the
discussion raises the point of what this classification would look
like if you were to ignore completely all the Population I, and
just focus attention on the Population II . . . " We stand on the
shoulders of giants. The great observer E. E. Barnard, in his
pioneering efforts to photograph the Milky Way, devoted the major
part of his life to identifying and numbering dusty "holes" and
dust lanes in our Milky Way. No one could have dreamt that the
pervasiveness of these cosmic dust masks (not only in our Galaxy
but also in galaxies at high redshift) is so great, that their
"penetration" is truly one of the pioneering challenges from both
space-borne telescopes and from the ground.
