1889: American inventor, Herman Hollerith
, patented his tabulator, the first device for data-processing.
It all began with Herman Hollerith
and his punched card, which was the main user interface to computers for the first few decades that computers existed.
The punch-card tabulator, a forerunner of the computer and one of the great innovations of the late nineteenth century, was the brainchild of a young engineer, Herman Hollerith
, the son of German immigrants who had fled to America in 1848 from the political and military turmoil then afflicting much of Europe.
Census Bureau first used a punch-card tabulating system, developed by Herman Hollerith
, to count the census for that year.
Crossing the Atlantic to the United States, we find Herman Hollerith
hard at work on the next big leap forward in computing - the use of electricity.
Its researchers conducted early experiments in x-ray technology and its factories built punched-card apparatus designed by Herman Hollerith
for the 1990 census.
The author's brief summation of the march of computing history includes Charles Babbage, the 19th-century astronomer and economist who sought to automate mathematics, just as the machines of the Industrial Age were converting factories to mass production; Herman Hollerith
, an engineer at the Massachusetts Institute of Technology, who built a punch-card tabulator for the national census in 1890; and Vannevar Bush, also of M.
census, statistician Herman Hollerith
invents an electromechanical machine that reads holes in perforated cards.
On this side of the Atlantic, Herman Hollerith
, seeing a business opportunity in a machine that could mechanically tabulate the U.
(1860-1929) was an American engineer who shared Babbage's love of tinkering.
patented a machine that helped sort statistical information for the 1890 U.
