Serial doodler, drafter, and brainstormer, New Hampshire–born Earl S. Tupper was an inventor obsessed with improving everyday household objects. His rough sketches, scrawled with a fountain pen over rapidly yellowing notebook paper, include an eyebrow shield to allow more precise penciling; adjustable glasses; hairpins that wouldn’t fall out; and garter hooks that remained fastened. “My purpose in life [is] to take each thing as I find it and . . . see how I can improve it,” he wrote.

Before 1930, refrigerators were not only bulky and expensive but extremely dangerous. Chemicals used as refrigerants—ammonia, methyl chloride, and sulfur dioxide—were not only toxic but highly combustible. In 1929 a leak in a methyl chloride refrigeration system caused an explosion that killed more than 100 people in a Cleveland hospital. It was no wonder that consumers preferred their old iceboxes. That would all change in 1930 with the invention of Freon by a General Motors researcher.
