Claim that Frederick Law Olmsted designed the grounds of Yerkes Observatory is misleading

Closer to the truth, I believe, that the grounds were designed by the architectural firm, Olmsted Brothers, comprised of John Charles Olmsted and Frederick Law Olmsted, Jr. in 1906, three years after the death of the senior Olmsted. See:

PROPOSAL FOR THE PURCHASE OF THE YERKES OBSERVATORY SITE IN WILLIAMS BAY, WISCONSIN prepared by Aurora University. The proposal cites John Olmsted as the landscape architect. See Historic Yerkes Landscape page 5.
Treemendous,Wisconsin Natural Resources Magazine See The Trees at Yerkes Observatory, at the bottom of the page.

I'll update the article myself when I have time; other editors are welcome to confirm these references and update as well. Gosgood 15:16, 20 February 2007 (UTC)[reply]

102 cm (40 inch) refractor at the Yerkes Observatory

The 102 cm (40 inch) refractor at the Yerkes Observatory is a landmark telescope and there is practically nothing about it in this article. This is a major oversite and i hope someone gets around to writing an article on it re: it's history, construction, place in the world as the worlds largest refractor...etc. 64.0.112.58 (talk) 16:03, 25 June 2008 (UTC)[reply]

Largest refracting telescope ever used?

The article claims it is 'the largest refracting telescope ever used'. I hate to be a stickler, but what about the Swedish 1 meter solar telescope finished in 2002? --Chetvorno^TALK 18:06, 30 June 2008 (UTC)[reply]

Refracting telescopes are made of large pieces of glass whose edges are rounded in order to make small visible areas larger at a certain point (like a magnifying glass). While I have not read the whole article, I find it highly unusual that they would make a refracting telescope which was dedicated to looking at the sun (it does not take up a small area comparatively). Even the eight inch refracting telescope that I used had to be covered so that only 2 inches or less of the area of the glass be available to accept the light from the sun. It is a large magnifying glass; have you ever used a magnifying glass to start a piece of paper on fire with the light from the sun focused onto it? Please reread that article and tell me if you think that this is a huge magnifying glass that they use to look at the sun with or not. The Yerkes telescope is a 40 inch magnifying glass and they started to use mirrored surfaces which need less length (which is possibly the real reason that this is the largest refracting telescope ever made). -- carol (talk) 21:06, 30 June 2008 (UTC)[reply]
