The first programming languages predate the modern computer
History of computing hardware - Wikipedia
Algol 60 was particularly influential in the design of later languages, some of which soon became more popular. The Burroughs B5000 was designed to be programmed in an extended subset of Algol.

In 1945, Konrad Zuse published details of his programming language Plankalkül. However, it was not implemented in his time and his original contributions were isolated from other developments because Germany was isolated during the war.

The first electronic stored-program digital computer to be proposedin the U.S. was the EDVAC (see below). The ‘First Draft of aReport on the EDVAC’ (May 1945), composed by von Neumann,contained little engineering detail, in particular concerningelectronic hardware (owing to restrictions in the U.S.). Turing's‘Proposed Electronic Calculator’, on the other hand,supplied detailed circuit designs and specifications of hardware units,specimen programs in machine code, and even an estimate of the cost ofbuilding the machine (£11,200). ACE and EDVAC differedfundamentally from one another; for example, ACE employed distributedprocessing, while EDVAC had a centralised structure.

F.H. Hinsley, official historian of GC&CS, has estimated thatthe war in Europe was shortened by at least two years as a result ofthe signals intelligence operation carried out at Bletchley Park, inwhich Colossus played a major role. Most of the Colossi were destroyedonce hostilities ceased. Some of the electronic panels ended up atNewman's Computing Machine Laboratory in Manchester (see below), alltrace of their original use having been removed. Two Colossi wereretained by GC&CS (renamed GCHQ following the end of the war). Thelast Colossus is believed to have stopped running in 1960.
