Thanks, Brian, for pointing out the Wikipedia page on large refractors. Wow,
what a list. There's one large refractor that I didn't see on the list (but it
may be there). It's the Bruce Double Astrograph at Heidelberg. It consists of
two co-mounted 16 inch f/5 refractors, and it discovered many asteroids and
high proper-motion stars. Catherine Bruce, an American, donated $10,000 for the
telescope at the urging of Max Wolf who was an awesome salesman and astronomer.
Wolf contracted with John Brashear to build it.

I wonder how many other 120 year old telescopes are still up and working
around the world? Lick, Yerkes, Naval Observatory and Harvard are all I
can think of. Fascinating that so many of them would be Clark
refractors. I know that there are some British telescopes that are in
that age group.
