All four answer options are famous English potters whose names are still known today in the brand names that they founded.

Josiah Wedgwood (12 July 1730 – 3 January 1795) was born into the pottery community in Burslem, North Staffordshire, the eleventh and last child of potter Thomas Wedgwood and Mary Wedgwood. By the age of nine, he was proving himself to be a skilled potter. He survived a childhood bout of smallpox to serve as an apprentice potter under his eldest brother. However, smallpox left him with a permanently weakened knee: this disability made it impossible to work the foot pedal of a potter's wheel. As a result, Josiah concentrated from an early age on pottery design.

Not only did Josiah Wedgwood have an eye for great beauty in his pottery design he also focused on practicality in both the ceramic productions and in methods. He created the concept of the production line in pottery: previously each part of the process took place in a separate building.

The most important of Wedgwood's early achievements in vase production was the perfection of the black stoneware body, which he called "basalt". This body could imitate the colour and shapes of Etruscan or Greek vases which were being excavated in Italy. In 1769, "vases was all the cry" in London; he opened a new factory called Etruria, north of Stoke. Wedgwood became what he wished to be: "Vase Maker General to the Universe".
