For example, “the meetings are much more informal now, certainly in terms of dress,” according to C. Dale Poulter, a University of Utah professor and editor of JOC, who attended his first NOS in 1969. “You always wore a suit and tie, or at least a sport coat and a tie.” Today, you might see Hawaiian shirts and flip-flops.
Like any meeting, NOS has weathered technological winds of change. Cornell University’s Jerrold Meinwald recalled toting his presentation to the 1963 meeting, not on a laptop but on fragile glass slides, about 3 × 5 inches each. “They weighed a ton,” he said.
By the late 1960s, glass slides gave way to slides made with camera film. Most slides were hand drawn and then photographed, Poulter said. In humid environments, slides could warp, he explained. “Sometimes, the intensity of the projector lamp would burn the slides. I saw a lot of presenters move rapidly through a talk because their slides were getting burned.
“For someone who’s had to go through all that,” Poulter continued, “ChemDraw and PowerPoint are like dying and going to heaven.”Scroll down and take the quiz about NOS history -- it's quite challenging!
