At the dawn of the twentieth century, a young scientist faced the limitations of existing statistical theory when applied to research involving small samples. He worked for the Guinness brewery in Dublin, and his investigations of the quality of raw ingredients, the nature of the production process, and the resulting quality of the end product—beer—often entailed decidedly small samples of 10 or fewer experiments. The scientist was William Sealy Gosset (1876–1937). He is better known by his pseudonym “Student,” which, for proprietary reasons, his employer required him to use when publishing.
