Q

Herman Hollerith

A

Solved the 1890 Census problem. Inspired by sheets of paper in an organelle. Hollerith’s machine kept track of information w/ holes, like a scantron.

17
Q

Computer’s ancestors

A

Office automation devices that had word processing, information storage + retrieval, and financial analysis.

18
Q

Typewriter

A

Invented by Christopher Lathan Sholes. Manufactured by Philo Remington in 1873.

19
Q

Filing Cabinet

A

Invented by the Rand Kardex Company. Was efficient and expandable.

20
Q

Adding Machine

A

Invented by Dorr E. Felt and William S. Burroughs. Designed for addition.

21
Q

Cash Register

A

Invented by James Ritty and marketed by John H. Patterson. Showed purchase amount to clerks and customers.

22
Q

Comptometer

A

Invented by Dorr E. Felt. Made around the same time that Burroughs invented a calculator. Could not print.

23
Q

Thomas J. Watson Sr.

A

Fired from the National Cash Register Company. Founded Computing Tabulating Recording Company (now IBM)

24
Q

Differential Analyzer

A

Invented by Vannevar Bush from 1928-1931. Could elaborate electronics to solve differential equations. Could tackle engineering problems.

25
Howard Aiken
Wanted to use calculating machines to solve nonlinear equations. Created the Mark I.
26
Harvard Mark I
Invented by Howard Aiken. Harvard rejected his funding but IBM agreed. Could add, subtract, multiply, and perform logarithms and trigonometric functions.
27
The Atanasoff-Berry Computer (ABC)
Created by John Atanasoff and Clifford Berry at Iowa State. Invented to solve linear equations. Was abandoned in 1942.
28
