Thanks for posting those links.  An interesting side note is the 2 links to the articles by Dr. Donald Menzel.  He started his career as a student at Denver University Chamberlin Observatory, where I volunteer.  We still regularly use the 20-inch Clark for public nights and open houses.  During the 2003 opposition I  imaged Mars using the 20-inch Clark refractor with a ToUcam.  While I took my Macbook and DBK camera  there a couple weeks ago to image Mars again, the R.A. lock had seized up and so we have no tracking until fixed.  I fwd'd your links to the Denver Astro Society list.

p.s. if you 'flip' the pages back on the first PM link you'll find an article about the first cathode ray tube, which only used -'one pound of radium!
