Charles Babbage was an English mathematician, philosopher, inventor, and mechanical engineer who designed the Difference Engine and, more importantly, the Analytical Engine. The Analytical Engine is considered the conceptual forerunner of the modern digital computer, incorporating features like an Arithmetic Logic Unit (ALU), basic flow control, and integrated memory, which are fundamental to today's computers. Although it was never fully built in his lifetime, his detailed designs and theoretical work laid the foundational principles for future computer development.
