William Lowell Putnam any dramatic changes in the Observatory's staff or location. Thus, an Observatory expedition and possibly a permanent move to South America was postponed, effectively establishing the Observatory in Flagstaff, Arizona. Despite his conviction that he should not make any major changes to the Observatory, Putnam did become embroiled in the controversy surrounding T. J. J. See. See was employed at Lowell Observatory at that time, but was both an extremely unpopular man and also regarded as a bad scientist. Three Observatory employees had already resigned due to See's poor treatment of them, and Douglass began working to remove See from
United States Naval Observatory Flagstaff Station astronomical interferometer of the venerable and proven Michelson Interferometer design. As noted, the majority of interferometric science and operations are funded and managed by NOFS; however, Lowell Observatory and NRL join in the scientific efforts through their fractions of time to use the interferometer; 85% Navy (NOFS and NRL); and 15% Lowell. NPOI is one of the few major instruments globally which can conduct "optical" interferometry. See an illustration of its layout, at bottom. NOFS has used NPOI to conduct a wide and diverse series of scientific studies, beyond just the study of absolute astrometric positions of stars. Additional NOFS
