Herman hollerith biography
Herman Hollerith was a pioneer in the field of data processing and is best known for his development of the punched card tabulating machine, which revolutionized the way data was processed and analyzed.
Hollerith was born in Buffalo, New York in 1860, the son of German immigrants. He received his early education in public schools before enrolling in the City College of New York, where he studied engineering. After graduation, Hollerith worked as a civil engineer for a short time before enrolling in the Columbia School of Mines, where he received a degree in electrical engineering.
In the 1880s, Hollerith began working for the United States Census Bureau, where he was tasked with finding a more efficient way to process and analyze the vast amounts of data collected during the census. At the time, data was collected and analyzed by hand, which was a slow and error-prone process. Hollerith realized that the use of punched cards, similar to those used in Jacquard looms, could be used to process and analyze data more efficiently.
In 1884, Hollerith developed a machine that could read and process data stored on punched cards. This machine, known as the Hollerith Tabulating Machine, was used by the Census Bureau to process data from the 1890 census and proved to be a huge success. It allowed the census to be completed in just two years, compared to the seven years it took to complete the 1880 census.
After the success of the Hollerith Tabulating Machine, Hollerith founded the Tabulating Machine Company in 1896, which later became International Business Machines (IBM). Under Hollerith's leadership, the company developed and marketed a variety of data processing equipment, including punched card tabulators and sorters, as well as other related products.
Hollerith's innovations had a major impact on the field of data processing and laid the foundation for the development of modern computers. He received numerous awards and accolades for his work, including the Franklin Institute's Elliott Cresson Medal in 1906. Hollerith died in 1929, but his legacy lives on through his contributions to the field of data processing and the continued success of IBM.

There is a rather strange twist to this story for the engineer who was in charge of the development of the rival machines at the Census Bureau, James Powers, was strangely allowed to patent these more advanced machines in his own name. In 1911, Herman Hollerith merged Tabulation Machine Company with three other companies to create Computing Tabulating Recording Company. While at Columbia, Herman took the standard course of study which required both classes and practical work. John Shaw Billings, head of the Department of Vital Statistics. Hollerith was also required to visit local industries, such as metallurgical and machine shops, in order to understand how they functioned.

Schurz, a man of tremendous influence, who left Germany after the Revolution just like Hollerith, moved to US in 1852, and later became a Union general in the Civil War, US senator, and US Secretary of the Interior from 1877 until 1881 under the presidency of Rutherford Hayes. Hollerith thought he could design the machine, and later offered to include Billings in the project. Pins over the holes would pass through the cards to be submerged in mercury, which created electrical circuits that yielded hits on counters. Meanwhile, he devised a system for numerically coding data. Engineering developments improved the accuracy of the pin going through the hole in the card to make an electrical connection with mercury placed beneath. He worked there from 1884 to 1890.

This control system allowed for flexibility and various levels of complexity in the patterns," noted Mark Russo, in The World's First Statistical Engineer. A repeat performance in 1900 confirmed the efficacy of the system by reducing the time to process to one quarter of the previous census and cutting labor costs considerably. The problems with Hollerith's continuous paper strip were that it was easy to tear, it was difficult to find a specific piece of information on the strip, and it was almost impossible to re-sort information. As an engineering student, he took chemistry, physics, and geometry, as well as courses in surveying and graphics, and surveying and assaying. This military use gave Hollerith added prestige, increased sales, and the financial resources needed to make improvements. His work revealed the problems of dealing with large amounts of data by hand. The 1880 census took seven and a half years to complete.
His employees never knew what he was going to do next. He died of heart failure on November 17, 1929, in Washington, D. While he worked at the Massachusetts Institute of Technology Hollerith began his first experiments. People of this zodiac sign like romance, to sleep, spiritual themes and dislike the know-it-all, to be criticized, and cruelty of any kind. Innovating card-feed mechanism and key punch could only read selected census cards. . Patent Office and began his career as a solo inventor and entrepreneur.
He liked good cigars, fine wine, Guernsey cows, and money. Hollerith's system was first tested on tabulating mortality statistics in Baltimore, New Jersey in 1887 and again in New York City. His machines were utilized by the US Census Bureau to organize data during the 1890 census. The total population of the United States in 1890 was found to be 62, 622, 250. In 1884 he obtain a post in the U.
Herman Hollerith Biography
After graduation, he met Kate at the Census Bureau, where he used to work. He found that in most respects the function of the Jacquard loom was too far removed from what might be useful to the census work, however he did realise that the punched cards were an efficient way to store information. This appointment was very significant because it was in solving the problems of analysing the large amounts of data generated by the 1880 US census that Hollerith was led to look for ways of manipulating data mechanically. Hollerith stayed at the merged company as a consulting engineer until he retired in 1921. Never a man to leave things as they were, Hollerith immediately found new markets for his machines in the business world. His final job was for the U.
He is known for inventing the tabulating machine. After this incident, Hollerith devoted himself entirely to commercial work. Herman Hollerith was born in 1860 in Buffalo, N. Billings had recommended that he study a Jacquard loom, a mechanical loom or weaving machine, for inspiration. He also obtained some practical mining experience during summer vacations in the mines of northern Michigan. He died at home in Washington, D.
Herman Hollerith Biography, Life, Interesting Facts
Hollerith designed punches specially made for his system, the Hollerith Electric Tabulating System. Herman Hollerith in 1880 After graduating Hollerith became an assistant to one of his teachers, Professor Trowbridge, who was so impressed of his mind that he asked him to become his assistant. At that time he was entirely engaged in the design and improvement of his electric counting machines, and they proved to be a great success, as he won a contract from the Census Office when it reopened for the 1890 census, then his machines were used for censuses of Canada, Norway, Austria, Russia, and other countries. His electric counting equipment significantly shortened tabulation time for the 1890 census, which was completed in half the time it took for the 1880 census. In 1860s he was already a big landowner, who rented his lands to farmers, and took part in the Civil War, serving in the local guard of Buffalo. In his last years, Hollerith suffered from heart disease. This was either good luck or a brilliant career move depending on how far sighted Hollerith was in seeing that he would be in the best possible position to make full use of skills learnt in the patent office in patenting his own inventions.

Hollerith acknowledged near the end of his life the help that Billings had given him. The counting was completed by 12 December 1890 having taken about three months to process instead of the expected time of two years if counting had been done by hand. Although Hollerith worked with the company he founded as a consulting engineer until his retirement in 1921, he became less and less involved in day-to-day operations. Trowbridge, who was a consultant to the US Bureau of the Census, introduced Hollerith to John Shaw Billings, who employed him as an assistant in his work on the statistical analysis of the 1880 census. In the meantime, Hollerith's system was purchased for use in several European census activities, and he formed a company, the Tabulating Machine Company, to service these opportunities. Herman Hollerith is regarded as one of the seminal figures in the development of data processing.
