Louis Dijour Smullin, left, talks with colleagues with maser that measured distance to the moon.

Original caption: ""Louis D. Smullin, '39, (left) was the first to bounce a laser beam off the moon (the white speck at the upper left), using a telescope at Lincoln Laboratory in 1962. He joked that the trick would be easier if someone would put efficient reflectors on the moon -- which astronauts obligingly did a few years later to make careful measurements possible. In the center is Stanley Kass of Raytheon and at right, Giorgio Fiocco of the Research Laboratory of Electronics."
