▲Machines that a modern perspective might call machine tools have existed for millennia (for example, lathes and bow drills existed in ancient Egypt), but it was not until the later [[Middle Ages]] and the [[Age of Enlightenment]] that the modern concept of a machine tool—a class of machines used as tools in the making of other machines—began to evolve. Clock makers of the middle ages and [[polymath|renaissance men]] such as [[Leonardo da Vinci]] helped expand humans' technological milieu toward the preconditions for industrial machine tools. During the 18th and 19th centuries, and even in many cases in the 20th, the builders of machine tools tended to be the same people who would then use them to produce the end products (manufactured goods). However, from these roots also evolved an industry of '''machine tool builders''' as we define them today, meaning people who specialize in building machine tools for sale to others. The first machine tools offered for sale (i.e., commercially available) were constructed by [[Matthew Murray]] in England around 1800.<ref>Moore</ref> Others, such as [[Henry Maudslay]], [[James Nasmyth]], and [[Joseph Whitworth]], soon followed the path of expanding their entrepreneurship from manufactured end products and [[millwright]] work into the realm of building machine tools for sale.
