Never. There is a story that IBM declared something like this in the early 1950s, but there is no evidence for it.
Howard Aiken
Tommy Flowers designed the Colossus computer for Bletchley Park to crack the German High Command teletype cypher called Tunny. Ten machines were built and used from 1944 to 1945. While never used as a general-purpose electronic digital computer analysis of its design later showed it to have full general -purpose capability. The British kept two of these machines running from 1945 into the 1970s to break Soviet teletype cyphers, so they were not declassified until the 1980s and do not appear in most books on the history of computers.J. Presper Eckert and John Mauchly designed the ENIAC for the US Army Ballistics Research Laboratory. One machine was built in 1945. It was designed to be general-purpose and its first real program was to simulate Edward Teller's original hydrogen bomb design called the Classical Super. This job took 2 months to run (December 1945 and January 1946), after which ENIAC was declassified and demonstrated to the public in February 1946 making it the first general-purpose electronic digital computer known to the public.
Howard Homestead was created in 1825.

Howard Aiken
The IBM Automatic Sequence Controlled Calculator (ASCC), called the Mark I by Harvard University,[1] was the first large-scale automatic digital computer in the USA. It is considered by some to be the first universal calculator. The electromechanical ASCC was devised by Howard H. Aiken created at IBM, shipped to Harvard in February 1944, and formally delivered there on August 7, 1944 - mayur_vaghela@yahoo.co.uk
Digital computer development happened in several places at various times:London - 1830s Charles Babbage designs a mechanical digital Analytical Engine computer but does not build it.Cambridge - 1936 Alan Turing writes his paper "On Computable Numbers" which describes the Turing Machine, a hypothetical digital computer.Ames, IA - 1936 to 1942 John Vincent Atanasoff designs and builds electronic digital Atanasoff-Berry Computer with his graduate student Clifford Berry.Harvard - 1939 to 1942 Howard Aiken designs the electromechanical digital Automatic Sequence Controlled Calculator computer and IBM builds it, following a disagreement between Aiken and IBM the machine is renamed the Harvard Mark I.Dollis Hill/Bletchley Park - 1943 to 1944 Tommy Flowers builds electronic digital Colossus computer, the first programmable electronic digital computer. A total of 10 of these machines are built, making it the first digital computer built in quantity before UNIVAC I in 1952. All but 2 are destroyed in 1945 after the end of the war with Germany and the project is kept classified until the early 1980s more than 2 decades after the remaining Colossus computers had also been destroyed.Berlin - 1936 to 1945 Konrad Zuse builds electromechanical Z3 computer. This machine is destroyed in an Allied bombing raid.Philadelphia, PA - 1943 to 1945 Eckert and Mauchly build electronic digital ENIAC computer, the first programmable electronic digital computer publically announced contemporaneously to its construction.After WW2 development spread rapidly to many locations.
Alan Turing, I think. He made the computer, I am not to sure. Turing was British not American. The first American to invent a programmable computer was likely Vanevar Bush in 1929, but his was analog electromechanical, it was called the Differential Analyzer. The first American to invent an electronic digital computer was John Vincent Atanasoff, but his was not programmable, while it had no name at the time it was built it was later called the Atanasoff-Berry Computer. The first American to invent a programmable digital computer was Howard Aiken, but his was electromechanical, it was called the Harvard Mark I. The first programmable electronic digital computer was invented by Thomas Flowers of the British Post Office in 1942, called Colossus it was used to crack the German high command's cyphers (with 11 machines built prior to the end of the war, it was the only digital computer built prior to 1950 in a quantity greater than 1). The first Americans to invent a programmable electronic digital computer were John Mauchly and J. Presper Eckert, but their machine ENIAC was a dead end architecture that was very difficult to program. The first programmable electronic digital computer resembling modern ones in architecture, called the Manchester Baby, was built by the British in 1948, but it had a minuscule memory of only 32 words of 32 bits each. Practical programmable electronic digital computers resembling modern ones in architecture really had to wait for the early 1950s and by then inventions only covered improvements in specific design detail, not whole computers.

Howard Aiken is the original conceptual designer of one of IBM's earliest computers, the Harvard Mark I.
Charles Babbage in 1840s, but he never built it.First electronic computer built was Atanasoff-Berry Computer in 1942, but it wasn't programmable and was never patented.First programmable computer was Harvard Mark I, designed by Howard Aiken, built by IBM in 1942, but it wasn't electronic.First electronic programmable computer was ENIAC, designed by Eckert & Mauchly, built in 1945, but programming was cumbersome as it involved manually rewiring the connections between the 40 modules of the machine as well as setting manually roughly 1000 switches.First modern type electronic programmable computer that stored instructions and data in the same memory was the british EDSAC in 1948. Soon followed by the US EDVAC in 1949.Note: all above are digital computers, I am ignoring analog computers.
