Chemistry class, spring 1960

Professor Henry Muller (on the far left) assists a student in the chemistry lab. Besides Mr. Muller, there are either 5 students or 4 students and a lab technician in the photo. Two of the students are wearing protective goggles and it appears as if scientific experiments are in progress. A black and white composition notebook is open on the lab table, presumably for note taking. Clock on the back wall reads 9:15.
