As far back as 7,000 B.C., people were using closed gourds as jars. In 1520, Spanish conquistador Hernán Cortés recounted seeing Aztec ruler Montezuma serve a frothy cacao-based drink from a similar vessel.
Up until the mid-19th century, bartenders mixed drinks by “rolling” or “throwing” them, i.e. pouring their ingredients back and forth between two glasses, but in 1872, William Harnett of Brooklyn registered a patent for a device to efficiently mix up six cocktails at a time. It consisting of six covered tumblers and a plunger and rod system, which when activated caused the tumblers to move up and down to incorporate their contents. It didn’t prove to be an overwhelming success.
