  We present the fundamental properties of 87 stars based on angular diameter
measurements from the Navy Precision Optical Interferometer, 36 of which have
not been measured previously using interferometry. Our sample consists of 5
dwarfs, 3 subgiants, 69 giants, 3 bright giants, and 7 supergiants, and span a
wide range of spectral classes from B to M. We combined our angular diameters
with photometric and distance information from the literature to determine each
star's physical radius, effective temperature, bolometric flux, luminosity,
mass, and age.
