Developed an early fully transistorized computer, the Mailüfterl. Crucial in the creation of the formal definition of the programming language PL/I. 1938, 1945 Zuse, Konrad: Built the first digital freely programmable computer, the Z1. Built the first functional program-controlled computer, the Z3 in 1941. [59]
The first stored-program transistor computer was the ETL Mark III, developed by Japan's Electrotechnical Laboratory [50] [51] [52] from 1954 [53] to 1956. [51] However, early junction transistors were relatively bulky devices that were difficult to manufacture on a mass-production basis, which limited them to a number of specialized ...
Alan Turing, English computer scientist, mathematician, logician, and cryptanalyst. (circa 1930) Before the 1920s, computers (sometimes computors) were human clerks that performed computations. They were usually under the lead of a physicist. Many thousands of computers were employed in commerce, government, and research establishments.

From the first Apple computer to the COVID-19 vaccine, here are the most revolutionary inventions that were born in the U.S.A. in the past half-century.
The history of computing hardware spans the developments from early devices used for simple calculations to today's complex computers, encompassing advancements in both analog and digital technology. The first aids to computation were purely mechanical devices which required the operator to set up the initial values of an elementary arithmetic ...

Chinese inventor Liang Lingzan built the world's first fully mechanical clock; water clocks, some of them extremely accurate, had been known for centuries previous to this. This was an important technological leap forward; the earliest true computers, made a thousand years later, used technology based on that of clocks. [citation needed] 850
