Wasserman at the Anderson Mesa Station of the Lowell Observatory. Lewis E. Love (b. 1928), beloved physics teacher at Great Neck North High School from 1959 to 1997, inspired his students (including the discoverer) with his joy of teaching and love of physics. Although formally retired, he is now teaching elementary-school teachers how to teach science.
