Josiah or Yoshiyahu ( /dʒoʊˈsaɪ.ə/ or /dʒəˈzaɪ.ə/;Hebrew: יֹאשִׁיָּהוּ, Modern Yoshiyyáhu Tiberian Yôšiyyāhû, literally meaning "healed by Yahweh" or "supported of Yahweh"; Greek: Ιωσιας; Latin: Josias; c. 649–609 BC) was a king of Judah (641–609 BC) who instituted major reforms. Josiah is credited by most historians with having established or compiled important Jewish scriptures during the Deuteronomic reform that occurred during his rule.

Josiah became king of Judah at the age of eight, after the assassination of his father, King Amon, and reigned for thirty-one years, from 641/640 to 610/609 BC.

He is also one of the kings mentioned in the genealogy of Jesus in the Gospel of Matthew.

Josiah was the son of King Amon and Jedidah, the daughter of Adaiah of Bozkath. His grandfather Manasseh was one of the kings blamed for turning away from the worship of Yahweh. Manasseh adapted the Temple for idolatrous worship. Josiah's great-grandfather was King Hezekiah who was a noted reformer.

Josiah had four sons: Johanan, Eliakim (born c. 634 BC) by Zebudah the daughter of Pedaiah of Rumah, Mattanyahu (c. 618 BC) and Shallum (633/632 BC) both by Hamutal, the daughter of Jeremiah of Libnah.

Josiah Wedgwood (12 July 1730 – 3 January 1795) was an English potter, founder of the Wedgwood company, credited with the industrialization of the manufacture of pottery. A prominent abolitionist, Wedgwood is remembered for his "Am I Not a Man And a Brother?" anti-slavery medallion. He was a member of the Darwin–Wedgwood family. He was the grandfather of Charles Darwin and Emma Darwin.

Born in Burslem, Staffordshire, England, the twelfth and last child of Thomas Wedgwood and Margret Wedgwood (née Stringer; d. 1766), Josiah was raised within a family of English Dissenters. 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 Thomas Wedgwood IV. Smallpox left Josiah with a permanently weakened knee, which made him unable to work the foot pedal of a potter's wheel. As a result, he concentrated from an early age on designing pottery and then making it etc.

In his early twenties, Wedgwood began working with the most renowned English pottery-maker of his day, Thomas Whieldon, who eventually became his business partner in 1754. He began experimenting with a wide variety of techniques, an experimentation that coincided with the burgeoning of the nearby industrial city of Manchester. Inspired, Wedgwood leased the Ivy Works in the town of Burslem. Over the course of the next decade, his experimentation (and a considerable injection of capital from his marriage to a richly-endowed distant cousin) transformed the sleepy artisan works into the first true pottery factory.
