Herman Hollerith (1860-1929) Nacido en Buffalo, New York, el 29 de Febrero de 1860 era hijo de unos inmigrantes alemanes. Realizó estudios en el City College de New York a la edad de 15 años y se graduó de Ingeniero de Minas con altas distinciones en la Columbia School of Mines, a la edad de 19 años. Su primer empleo lo obtuvo en la Oficina de Censos en 1880. Posteriormente enseñó ingeniería mecánica en el Instituto Tecnológico de Massachusetts (MIT) y luego trabajó para la Oficina de Patentes del gobierno norteamericano. Hollerith empezó a trabajar con el sistema de máquinas tabuladoras durante sus dias en el MIT, logrando su primera patente en 1884. Desarrolló una prensa manual que detectaba los orificios en las tarjetas perforadas. Tenía un alambre que pasaba a través de los huecos dentro de una copa de mercurio debajo de la tarjeta, cerrando de este modo el circuito eléctrico. Este proceso disparaba unos contadores mecánicos y ordenaba los recipientes de las tarjetas, tabulando así en forma apropiada la información. La máquina de Hollerith era eléctrica y procesaba los hoyos en las tarjetas basándose en la lógica de Boole En 1880 se celebró un censo de población nacional en los Estados Unidos y tuvieron que transcurrir 7 largos años antes de que toda la información quedase procesada por el Buró de Censos, debido a que los datos levantados eran tabulados en papel. Por consiguiente se estimó que el próximo censo a celebrarse en 1890 tardaría unos 10 o 12 años en procesarse para obtener los resultados finales. Es por ello que el gobierno norteamericano convocó a una licitación para un sistema de procesamiento de datos que proporcionase resultados más rápidos.

1890 HERMAN HOLLERITH 1890 HERMAN HOLLERITH DESIGNS A SYSTEM TO RECORD CENSUS DATA. THE INFORMATION IS STORED AS HOLES IN CARDS, WHICH ARE INTERPRETED BY MACHINES WITH ELECTRICAL SENSORS. HOLLERITH STARTS A COMPANY THAT WILL EVENTUALLY BECOME IBM. Herman Hollerith , an employee of the census bureau with a Ph.D. in statistics, was granted a contract to develop an automated system. Using Jacquard's ideas, he invented a model that coded the census data as a series of holes punched in an eight-column card. The code was called Hollerith code and is still in use today. The electronic tabulating machines designed by Hollerith were able to read the information on the cards and process it electronically. The machines consisted of three parts: a tabulator, a sorter with compartments electronically controlled by the tabulator's counters, and a device to punch data onto cards. Hollerith's tabulating machines were the forerunners of today's data processing industry. [Back to Timeline]

Herman Hollerith's Self-Propelled Stoat Catcher After the success of his Tabulating Machine in the reading and counting of the 1890 United States Census, Herman Hollerith began considering other uses for his tabulation machine and the punched-card system. After considering various possible uses, Herman became interested in the idea of creating a self-controlled roving machine, capable of operating independently from external instructions. The machine was to be controlled by the same punched-card system as the Tabulation Machine. At this point, Herman became inexplicably interested in the pursuit and capture of Stoats. It is still unsure as to how he became interested in this particular past time. The sport of Stoat-Catching (or Grogbodogivalkoia to give it’s proper Albanian name), traditionally done with implements resembling lacrosse sticks (known as Borisiztrousa ) and using live gerbils as bait had been introduced to the United States by Albanian immigrants during the 1850s, but had largely died out by the 1880s. (One can only wonder if Herman had played this sport when young). Herman decided to construct his roving machine as a Self-Propelled Stoat Catcher. The Self-Propelled Stoat Catcher (or SPSC as it came to be known to the development team.) was operated by punched cards fed into the back of the machine. These cards contained the parameters for the Stoat-Catching match. This included the terrain, the boundaries of the match, and the numbers of stoats expected. The machine would read the cards, and behave accordingly.

The Hollerith Tabulating Machine Herman Hollerith (1860-1929), Columbia University School of Mines EM 1879, PhD 1890. Photo: IBM. After receiving his Engineer of Mines (EM) degree, Hollerith worked on the 1880 US census, a laborious and error-prone operation that cried out for mechanization. After some initial trials with paper tape , he settled on punched cards (pioneered in the Jacquard loom ) to record information, and designed special equipment to tabulate the results. His designs won the competition for the 1890 US census. These machines reduced a ten-year job to three months (different sources give different numbers, ranging from six weeks to three years) , saved the 1890 taxpayers five million dollars, and earned Hollerith an 1890 Columbia PhD*. During the 1890s, Hollerith's machines were also used for censuses in Russia, Austria, Canada, and Norway, and again in the US census of 1900. In 1911 Hollerith's company merged with two others to form the Computing-Tabulating-Recording Company (CTR), which changed its name to International Business Machines Corporation (IBM) in 1924. Austrian's Hollerith biography [ ] implies that Hollerith's doctorate was honorary: "It now seemed only fitting that the school to which he owed so much, and to which he was a credit, should award him an honorary degree. And indeed, Columbia's records show that at the school's June [1890] commencement he did, in fact, become Dr. Hollerith." (p.56)

Lochkarten 1/x Herman Hollerith und seine Lochkarten Der geniale Erfinder, der als erster mit Lochkarten arbeitete, gründete eine Firma, die sich zum größten Computerhersteller der Welt entwickelte (IBM). Herman Hollerith wurde 1860 in Amerika geboren. Nach einem Studium an der Columbia University arbeitete er als Assistent in der Volkszählungsbehörde der Vereinigten Staaten und wertete die Daten der Zählung im Jahre 1880 statistisch aus. Da alle Daten mühsam per Hand ausgewertet wurden, lagen bei der nächsten Zählung, zehn Jahre später, noch nicht einmal alle Ergebnisse der letzten Befragung vor. Hollerith glaubte fest daran, dieses Problem lösen zu können, und er ließ sich deshalb von dem National Census Office zum Patentamt in Washington versetzen. Bei seinem ersten Lösungsversuch übertrug Hollerith die Daten zunächst auf Papierbänder, die in verschiedene “Felder" unterteilt waren. Jedes einzelne symbolisierte eine bestimmte Kategorie wie z. B. männlich/ weiblich oder schwarz/weiß und wurde durch Löcher belegt. Die kreisrunden Löcher wurden später maschinell “gelesen". erhielt Hollerith seine ersten Patente. Während der nächsten Jahre arbeitete er an der Verbesserung seines Systems, das zunächst für die Krankheitsstatistiken der Armee und der schnell anwachsenden amerikanischen Städte eingesetzt wurde.

Why She Married Ben! Another of the many people who brought us to our present age of cyberspace was a man who came up with an easier way to deal with a great deal of information in a quick and timely manner. Herman Hollerith greatly advanced the carrying out of that constitutional mandate known as the Census. He went on to found a company which eventually became IBM - Big Blue. That makes him a pretty significant character. Like Charles Babbage, the English mathematician, Hollerith saw the value of using punch cards in which to hold information, but whether he got the idea from French automated loom-maker Joseph-Marie Jacquard or from watching a railroad conductor punch train tickets I am not sure. The 1880 U.S. Census evidently was a badly done job which was still under way in 1887. Working for the Census Bureau at the time, Hollerith, born in Buffalo, N.Y., in 1860 to German immigrant parents, saw that punch cards could both hold information and quickly and efficiently give it up through the use of electric circuits. With the use of these cards and a card reader, the 1890 Census was tallied within six months.

Hollerith klügelte ein System aus, wie man Daten auf Karten durch ausgestanzte Löcher verschlüsseln kann. Dieses Lochkartensystem bewährte sich bei statistischen Auswertungen und war für die Entwicklung des Digitalcomputers von Nutzen. Holleriths Maschine, die 1890 bei der Volkszählung in den USA zum Einsatz kam, "las" die Karten mittels elektrischer Kontakte: An den Stellen, wo sich Löcher befanden, wurde ein Stromkreis geschlossen, so dass die Löcher nachgewiesen und gezählt werden konnten.

"La violencia: un problema de todos. ¿Cómo influye en los niños?" Este proyecto fue llevado a cabo durante 1999 en el Instituto Herman Hollerith de Tucumán, Argentina, y gentilmente cedido para su publicación por la Sra. Maria Ines Baez de Sanchez, Directora de Nivel Inicial, EGB 1 y EGB 2. Esperamos que sirva de inspiración y guía para otros colegios interesados en el problema de la violencia, tanto dentro de las aulas como fuera de ellas. FUNDAMENTACIÓN: Durante casi cuatro décadas se criticó a los padres porque no sabían educar. Sin embargo no se tomaron medidas para enseñarles cual sería la forma correcta de hacerlo. Si ponían límites eran padres castradores. Si no los ponían , indiferentes o abandónicos. Entretanto los hijos crecieron en un marco de desconcierto que hoy se traduce en la falta de valores, la hostilidad y la violencia que nos lastima a todos. Cómo poner punto final a esta situación que deploramos, educando para la no violencia. OBJETIVOS DEL PROYECTO: Generar espacios de reflexión e intercambio entre los padres, para favorecer el análisis de situaciones en donde predominan conductas violentas y encontrar propuestas de cambio.

KennisQuiz.nl Herman Hollerith De Amerikaanse uitvinder Herman Hollerith (1860-1929) werd geboren in Buffalo, New York als zoon van Duitse immigranten. Herman kon gemakkelijk leren en verliet de middelbare school reeds op vijftienjarige leeftijd. Hollerith studeerde op zijn negentiende af aan de Columbia universiteit. Na een korte tijd te hebben gewerkt bij het Amerikaanse bureau voor volkstelling ging hij naar het Massachusetts Institute of Technology om mechanica te studeren. Na deze studie werkte hij bij het Amerikaanse Octrooi Bureau. Hollerith is voornamelijk bekend geworden door zijn uitvinding van de ponskaart. In papier worden gaten geponst waardoor op gemakkelijke wijze sorteringen konden worden verricht en optellingen konden worden gemaakt. Een bijkomend voordeel is, dat doordat de telling mechanisch wordt uitgevoerd, de kans op fouten aanmerkelijk kleiner is, dan bij handmatige tellingen. Het idee is eigenlijk simpel, want door de ponsgaten in het papier kan contact gemaakt worden en een elektrisch stroompje activeert een teller.
