£50 note. Background Birmingham had long been a centre of the ironworking industry. In the early 18th century the town entered a period of expansion as iron working became easier and cheaper with the transition (beginning in 1709) from charcoal to coke as a means of smelting iron. Scarcity of wood in increasingly deforested England and discoveries of large quantities of coal in Birmingham's county of Warwickshire and the adjacent county of Staffordshire speeded the transition. Much of the iron was forged in small foundries near Birmingham, especially in the Black Country, including nearby towns such as Smethwick and West Bromwich. The resultant thin iron sheets were transported to factories in and around Birmingham. With the town far from the sea and great rivers and with canals not yet built, metalworkers concentrated on producing small, relatively valuable pieces, especially buttons and buckles. Frenchman Alexander wrote that while he had seen excellent cane heads, snuff boxes and other metal objects in Milan, "the same can be had cheaper and better in Birmingham". These small objects came to be known as "toys", and their manufacturers as "toymakers". Boulton was a descendant of families from around Lichfield, his great-great-great-great grandfather, Rev. Zachary Babington, having been Chancellor of Lichfield. Boulton's father, also named Matthew and born in 1700, moved to Birmingham from Lichfield to serve an apprenticeship, and in 1723 he married Christiana Piers. The elder Boulton was a toymaker with a small workshop specialising in buckles. Matthew Boulton was born in 1728, their third child and the second of that name, the first Matthew having died at the age of two in 1726. Early and family life The elder Boulton's business prospered after young Matthew's birth, and the family moved to the Snow Hill area of Birmingham, then a well-to-do neighbourhood of new houses. As the local grammar school was in disrepair Boulton was sent to an academy in Deritend, on the other side of Birmingham. At the age of 15 he left school, and by 17 he had invented a technique for inlaying enamels in buckles that proved so popular that the buckles were exported to France, then reimported to Britain and billed as the latest French developments. On 3 March 1749 Boulton married Mary Robinson, a distant cousin and the daughter of a successful mercer, and wealthy in her own right. They lived briefly with the bride's mother in Lichfield, and
