The Beginnings

02. June 1890 The Hollerith machine is used for the US census and becomes the first major success in IT history. Nintendo was founded a year earlier.

1833 Charles Babbage begins work on the "Analytical Engine". Unfortunately I couldn't find out the exact start date.

24. June 1784 The architect Johann Helfrich von Müller invented the Müller machine in 1784, which anticipated the principles of later calculators.

01. January 1673 Gottfried Wilhelm Leibniz invents a functioning calculating machine for all four basic arithmetic operations.

23. Mai 1618 The Thirty Years' War shook all of Europe between 1618 and 1648.

Actually it was already 1100 B.C. when wooden slide rules and aids such as the abacus were invented in various cultures and improved over the centuries.

The Second World War claimed more than 60 million lives between 1939 and 1945.

German engineer Konrad Zuse completes the "Z3". The mainframe is considered to be the first functional computer.

In Great Britain "Colossus" cracked German radio messages, in the USA the mainframe computers Mark I (1944) and ENIAC (1946) were built.

The transistor was invented in Bell Labs, but later developments such as the field effect transistor are at least as important for the technical breakthrough.

The UNIVAC 1 is the first commercial computer. It is available for a price of one million US dollars. By the end of the year, there will be 31 computers worldwide.

The first modern mainframe computers are completed: Siemens 2002 (1957), NEAC 1101 (1958) and IBM 7000 (1959) are based on better transistors.
