JF Ptak Science Books Quick Post
Many years ago in D.C. I bought part of the estate library of Parmelee C. Daniels--the books had been passed down to the next generation, and after their passing some of those books came into my bookstore. Among them was this wonderful photograph, made by P.V. Reyes of Avalon California in 1923. But it wasn't until tonight that I could easily put together the history of the image. (And when I said "small mystery solved" I meant that it was a small mystery to me--no doubt there will be many others who will identify this instrument on first light).
I found that the photograph was made during the 1923 Solar Eclipse Expedition to Santa Catalina Island at Camp Wrigley, and was attended by Daniels and a host of the Big Names of astronomy of the 19-teens and 'twenties. Daniels was a professor at Drake University in Des Moines, and the school's telescope was packed up and made the trip to the Pacific. I do believe that this is the 8.5-inch refractor that was the gift to the school of General Drake in 1893, although I could be wrong.
Here's the image of the telescope (with Daniels standing on the box, President of Drake University and astronomy professor Dr. Morehouse, and Prof. Edwin B. Frost. The image comes from the University of Chicago:

And so the story of this photograph gained some life tonight by me simply plumbing the intertubes for information. Unfortunately I do not know the identity of the boy in the sailor's suit.
I received the following information on the telescope, generously supplied by Bart Fried of the Antique Telescope Society:
8 1/4" Brashear/Warner&Swasey refractor, 1894. (Curiously, in a dedicatory article in the 1922 issue of "Popular Astronomy" it is described by the chief astronomer at Drake University, Daniel Morehouse as a 9" telescope). According to Kirby-Smith (U.S. Observatories, Van Nostrand Reinhold), it has an interchangeable front flint element for visual or photographic work, and has a 5" doublet Brashear camera and a polarizing solar eyepiece. Possibly also, a filar micrometer and a spectroscope.
Two other short articles of interest: "The expedition from the Yerkes observatory for observing the total solar eclipse of September 10, 1923, at Camp Wrigley" is found here: http://adsabs.harvard.edu/full/1924PA.....32..205F and http://articles.adsabs.harvard.edu/full/1922PA.....30..461M
