Roger Putnam which was under-utilized due to poor viewing conditions and low elevation. Putnam led the negotiations which permanently moved the telescope to Lowell Observatory's Anderson Mesa site (in Arizona). The telescope was operated by Lowell Observatory in partnership with the Ohio State University and Ohio Wesleyan, and purchased by Lowell in 1998. Putnam brought Perkins's telescope to the Arizona observatory as well. The Observatory's existing telescope had cracked in 1964 while staff attempted to update its optical system. The Perkins mirror did not stay at Lowell for long, returning to Perkins' control in 1969. The Lowell Observatory retained the mount, however.
National Optical Astronomy Observatory shape the System and gain steady, state-of-the-art research capabilities of all apertures for open, merit based science. A future major capability for the US system is an Extremely Large Telescope with diameter up to 30 meters. Two private consortia are currently working on such projects which may be operational before the end of the decade. These are the Thirty Meter Telescope and Giant Magellan Telescope. NOAO is working with both projects in planning for potential future involvement of the broad US community through operational support funding by the NSF.
