Many modern computer principles can be traced back to which inventor who developed the idea of a mechanical digital computer in the 1830s?

The inventor who developed the concept of a mechanical digital computer in the 1830s is Charles Babbage. He is often regarded as the "father of the computer" for his pioneering work on the Analytical Engine, which was designed to be a general-purpose computing machine capable of performing any calculation. Babbage's design included features that are fundamental to modern computers, such as the use of an arithmetic logic unit, control flow through conditional branching, and memory to store numbers and intermediate results.

Babbage's vision of a programmable computer laid the groundwork for later developments in computing technology. His work was instrumental in advancing the concept of mechanical computation, even though the technology of his time did not allow him to fully realize his designs. The Analytical Engine was never completed, but his ideas influenced generations of engineers and computer scientists, establishing foundational principles for the digital age.
