Blaise Pascal - Pascaline
Created in 1642, the Pascaline was made to perform addition, but it never worked. -
Stepped Reckoner
Created by Gottfried Wilhelm Leibniz in around 1672, this device was made to add, subtract, multiply, divide, and square roots, but malfunctioned a lot. It's parts were ahead of it's time.

Ada Byron (Countess of Lovelace)
First programmer and stated that no computer no matter how powerful could ever think which stays true to this day. -
Herman Hollerith (IBM)
In 1911 four corporations, including Hollerith's firm, were consolidated to form the Computing-Tabulating-Recording Company (CTR). Under the presidency of Thomas J. Watson, it was renamed International Business Machines Corporation (IBM) in 1924.

ABC (First electronic computer)
The Atanasoff Berry Computer, later named the ABC, was built at Iowa State University from 1939-1942 by physics professor Dr. John Vincent Atanasoff and his graduate student, Clifford Berry. Also used a binary system of 1s and 0s still used today.

Mark 1 (1944)
Created by Harvard University, the Mark I had 60 sets of 24 switches for manual data entry and could store 72 numbers, each 23 decimal digits long. It could do 3 additions or subtractions in a second. A multiplication took 6 seconds, a division took 15.3 seconds, and a logarithm or a trigonometric function took over one minute.

EDVAC
Made by John Von Neumann, the EDVAC (Electronic Discrete Variable Automatic Computer) was one of the earliest electronic computers. Unlike its predecessor the ENIAC, it was binary rather than decimal, and was a stored program computer.

Transistor (1947)
The transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit.

EDSAC
Created by Maurice Wilkes and his team; the Electronic Delay Storage Automatic Calculator (EDSAC) was an early British computer. Inspired by John von Neumann's seminal First Draft of a Report on the EDVAC, the machine was constructed by Maurice Wilkes and his team at the University of Cambridge Mathematical Laboratory in England. EDSAC was the second electronic digital stored-program computer to go into regular service

John Von Neumann (Idea of stored program)
John Von Neumann had the idea of a stored program in CPU to control all functions inside of the computer. -
UNIVAC I
The UNIVAC I (UNIVersal Automatic Computer I) was the first commercial computer produced in the United States.[1] It was designed principally by J. Presper Eckert and John Mauchly, the inventors of the ENIAC. Design work was started by their company, Eckert–Mauchly Computer Corporation, and was completed after the company had been acquired by Remington Rand (which later became part of Sperry, now Unisys).

ENIAC
This computer was made secretly to calculate WWII missile trajectories, but the computer was finished after the war was finished. It solved problems that a team of mathematicians needed three days to finish in 20 seconds. It weighed 30 tons, and was 1500 sq ft. (The size of an average home) -
IBM Model 650
The IBM 650 Magnetic Drum Data-Processing Machine is one of IBM's early computers, and the world’s first mass-produced computer. It was announced in 1953 and in 1956 enhanced as the IBM 650 RAMAC with the addition of up to four disk storage units.

Integrated Circuits (ICs) Computer Chips
Created by Werner Jacobi, he patented the idea of an IC. An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a microchip) is a set of electronic circuits on one small plate ("chip") of semiconductor material, normally silicon.

IBM System 360
The IBM System/360 (S/360) is a mainframe computer system family that was announced by IBM on April 7, 1964, and delivered between 1965 and 1978.[1] It was the first family of computers designed to cover the complete range of applications, from small to large, both commercial and scientific. This computer had difficulty keeping up to manufacturing speeds due to demand. Was also cheaper so hospitals and universities could afford.

Microprocessor
Originally created by Marcian Hoff in 1970; A microprocessor is a computer processor which incorporates the functions of a computer's central processing unit (CPU) on a single integrated circuit (IC), or at most a few integrated circuits. The microprocessor is a multipurpose, clock driven, register based, programmable electronic device which accepts digital or binary data as input, processes it according to instructions stored in its memory, and provides results as output. -
Altair (1975)
Created by []; The Altair 8800 is a microcomputer designed in 1974 by MITS and based on the Intel 8080 CPU. Interest grew quickly after it was featured on the cover of the January 1975 issue (published in late November 1974) of Popular Electronics, and was sold by mail order through advertisements there, in Radio-Electronics, and in other hobbyist magazines. -
Apple Computer (1976)
Apple Computer 1, also known later as the Apple I, or Apple-1, was a desktop computer released by the Apple Computer Company (now Apple Inc.) in 1976. It was designed and hand-built by Steve Wozniak. Wozniak's friend Steve Jobs had the idea of selling the computer. The Apple I was Apple's first product, and to finance its creation, Jobs sold his only means of transportation, a VW Microbus, and Wozniak sold his HP-65 calculator for $500.

Bill Gates
Bill Gates has created a BASIC language interpreter in 1975, has founded Microsoft in 1977, and developed MS-DOS for PCs and Windows. -
IBM-PC (1981)
The IBM Personal Computer, commonly known as the IBM PC, is the original version and progenitor of the IBM PC compatible hardware platform. It is IBM model number 5150, and was introduced on August 12, 1981. It was created by a team of engineers and designers under the direction of Don Estridge of the IBM Entry Systems Division in Boca Raton, Florida.

Personal Computer
A personal computer (PC) is a general-purpose computer whose size, capabilities, and price make it feasible for individual use. PCs are intended to be operated directly by an end-user with only a general knowledge of computers, rather than by a computer expert or technician. The computer time-sharing models that were typically used with larger, more expensive minicomputer and mainframe systems, to enable them be used by many people at the same time, are not used with PCs. -
Bluetooth
Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz) from fixed and mobile devices, and building personal area networks (PANs). Invented by telecom vendor Ericsson in 1994, it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization.

First Smartphone
A smartphone is a mobile phone with an advanced mobile operating system which combines features of a PC operating system with other features. Smartphones, which are usually pocket-sized, typically combine the features of a cell phone, such as the abilities to place and receive voice calls and create and receive text messages. In 1999, the Japanese firm NTT DoCoMo released the first smartphones to achieve mass adoption within a country.
