Drawing. The Analytical Engine was the first fully-automatic calculating machine. Charles Babbage (1792-1871) first conceived the idea of an advanced calculating machine to calculate and print mathematical tables in 1812. This machine was designed to evaluate any mathematical formula and have even higher powers of analysis than his original Difference Engine. Only part of the machine was completed before Babbage's death in 1871.
