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.
