Zuse fled the German capital after the defeat of Nazi Germany and later released the world's first commercial digital computer, the Z4, in 1950, according to O'Regan.ġ941: Atanasoff and his graduate student, Clifford Berry, design the first digital electronic computer in the U.S., called the Atanasoff-Berry Computer (ABC). The machine was destroyed during a bombing raid on Berlin during World War II. The pair decide the name of their new company by the toss of a coin, and Hewlett-Packard's first headquarters are in Packard's garage, according to MIT.ġ941: German inventor and engineer Konrad Zuse completes his Z3 machine, the world's earliest digital computer, according to Gerard O'Regan's book "A Brief History of Computing(opens in new tab)" (Springer, 2021). Turing is later involved in the development of the Turing-Welchman Bombe, an electro-mechanical device designed to decipher Nazi codes during World War II, according to the UK's National Museum of Computing(opens in new tab).ġ937: John Vincent Atanasoff, a professor of physics and mathematics at Iowa State University, submits a grant proposal to build the first electric-only computer, without using gears, cams, belts or shafts.ġ939: David Packard and Bill Hewlett found the Hewlett Packard Company in Palo Alto, California. The central concept of the modern computer is based on his ideas. Turing machines are capable of computing anything that is computable. taxpayer approximately $5 million, according to Columbia University Hollerith later establishes a company that will eventually become International Business Machines Corporation (IBM).ĮARLY 20TH CENTURY1931: At the Massachusetts Institute of Technology (MIT), Vannevar Bush invents and builds the Differential Analyzer, the first large-scale automatic general-purpose mechanical analog computer, according to Stanford University.ġ936: Alan Turing, a British scientist and mathematician, presents the principle of a universal machine, later called the Turing machine, in a paper called "On Computable Numbers…" according to Chris Bernhardt's book "Turing's Vision" (The MIT Press, 2017). The machine, saves the government several years of calculations, and the U.S. Merzbach's book, "Georg Scheutz and the First Printing Calculator" (Smithsonian Institution Press, 1977).ġ890: Herman Hollerith designs a punch-card system to help calculate the 1890 U.S. The machine is significant for being the first to "compute tabular differences and print the results," according to Uta C. "Lovelace also adds a step-by-step description for computation of Bernoulli numbers with Babbage's machine - basically an algorithm - which, in effect, makes her the world's first computer programmer." Bernoulli numbers are a sequence of rational numbers often used in computation.ġ853: Swedish inventor Per Georg Scheutz and his son Edvard design the world's first printing calculator. Her annotations, simply called "notes," turn out to be three times as long as the actual transcript," Siffert wrote in an article for The Max Planck Society. "She also provides her own comments on the text. ![]() ![]() According to Anna Siffert, a professor of theoretical mathematics at the University of Münster in Germany, Lovelace writes the first program while translating a paper on Babbage's Analytical Engine from French into English. Funded by the British government, the project, called the "Difference Engine" fails due to the lack of technology at the time, according to the University of Minnesota.ġ848: Ada Lovelace, an English mathematician and the daughter of poet Lord Byron, writes the world's first computer program. Early computers would use similar punch cards.ġ821: English mathematician Charles Babbage conceives of a steam-driven calculating machine that would be able to compute tables of numbers. ![]() 19TH CENTURY1801: Joseph Marie Jacquard, a French merchant and inventor invents a loom that uses punched wooden cards to automatically weave fabric designs.
