example of a system used for checking railway tickets, although his brother claimed

which Hollerith would have been familiar"

Countess Augusta Lovelace(daughter of Lord Byron) was his assistant and couldbe identified as the first computer programmer.Important foundation work was started by GeorgeBoole (1815–1864; British/Irish mathematician) whodeveloped an analysis of logic in 1847 and Booleanalgebra later became the cornerstone of modern computer design. Herman Hollerith (1860–1929;American inventor) meanwhile devised a method in1880 for automating the process of data handling intoan electromechanical counter using a series of cardswith punched holes. A similar method was alreadybeing used by the weaving industry for controllingtheir machines. In 1911 Hollerith merged with threeother companies to form the Computing TabulatingRecording Company, later to become part of IBM.
Hollerith took a position at the Massachusetts Institute of Technology in 1882 and taught mechanical engineering. He remained interested in the problem of automating the tabulated census data and examined the workings of the Jacquard loom to see if it could assist. The main feature of the Jacquard loom that he considered applicable was its use of punched cards, as these were an efficient way of storing information. He also observed that it should be possible to punch information onto a card, as a conductor might do on a train. Hollerith conducted a number of experiments at the institute and initially employed a paper tape rather than cards. A pin could go through a hole in the tape and complete an electrical circuit, and Hollerith later replaced paper with cards as these offered a more effective solution.

In the Computer History Museum in Mountain View, California, a veri-
table warehouse of machinery is on display. Here are a Jacquard loom
and Hollerith punched card machine, the Cray 7600 supercomputer and
the JOHNNIAC.
The weaving machine, which had come into universal use in the production of decorative fabrics, was a familiar and still fascinating contraption to those with even a passing knowledge of textiles. Hollerith was particularly familiar with the details of the Jacquard device, having previously investigated the device as part of an abortive weaving business venture.
While at MIT, Hollerith made what he would later call his “first crude experiments” on the census machine. Like the player-piano roll, his first approach involved punching holes in a long strip of paper, in this case with one row for each person.
Two incidents contributed to Hollerith's solution: conversations with Census Bureau colleague, Dr. John Shaw Billings, about count mechanization and the Jacquard loom card system, and observations of a railroad conductor punching riders' tickets for identification purposes.
After receiving his Engineer of Mines (EM) degree at age 19, 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 -- a tabulator and sorter -- to tally the results. His designs won the competition for the 1890 US census, chosen for their ability to count combined facts. These machines reduced a ten-year job to three months (some sources give different numbers, ranging from six weeks to three years), saved the 1890 taxpayers five million dollars, and earned him an 1890 Columbia PhD¹.

It seems likely that he was also influenced by an automated
loom invented by the Frenchman, Joseph Marie Jacquard, about
eighty years earlier. Jacquard looms in Hollerith's time routinely
produced very intricate patterns guided by a sequence of thousands of punched cards, each with holes punched so as to specify
one step of the process. If not from other sources, he would surely
have learned about the Jacquard loom from a brother-in-law who
was involved in the silk-weaving business
He graduated from the Mowry and Goff School in Providence in 1891 and from the Massachusetts Institute of Technology in 1895. After graduation, he was employed by the Textile-Finishing Machinery Company of Providence
In 1882, Hollerith joined the Massachusetts Institute of Technology faculty, where he taught mechanical engineering for only one year; apparently, the thought of having to repeat teaching the same material the following year did not appeal to him. He was continuing to think about automating the census and first experimented with punched paper tape. The impossibility of reordering the information on the tape turned his thoughts to punched cards and solidified his ideas. He returned to Washington, DC and worked for a year as a patent examiner, gaining invaluable knowledge of the intricacies of that arcane art. He quickly applied this knowledge and filed a patent in 1884 for his method of automating the processing of census data.

When asked how he first had the idea of a census machine he would reply "chicken
salad" and then explain. When he first came to Washington he joined a boat club and
often rowed on the Potomac River. The club once had an evening entertainment at
which one of Dr. Billings' daughters, seeing father enjoying the chicken salad, invited
him to come to supper with them to have some of her mother's salad. It was at this
supper that Dr. Billings suggested the need for a machine to do the purely mechanical
work of tabulating population and similar statistics. Father talked the matter over
with Dr. Billings, who suggested using cards with the description of the individual
shown by notches in the edge of the card and a device something like a type-distributing
machine. Father went to Mr. Leland, who was in charge of the Population Division of
the Census Office, and asked to be taken on as a clerk to learn the nature of the job.
After studying the problem, father told Dr. Billings "to go in with him," but he was not
interested; his only wish was to see the problem solved
Perforations to allow elec-trical contacts was not a new idea: the automatictelegraph, for example, operated similarly. Whatwas new was the coding of the data and the useof the contact for counting.Hollerith soon realized that the continuousstrips were impractical, since tabulating somespecific group required passing through a greatdeal of paper. (This is the same problem we havewith non-random access devices like magnetictape today.) He then struck on the idea of usingcards rather than continuous rolls of paper. It isnot clear where he got this idea and he neverclaimed to have invented the data card which eventoday bears his name. One anecdote suggests heobserved a railroad conductor punching pas-sengers’ profiles on a ticket. Indeed, among hispersonal effects was found a conductor’s punchstamped with a patent date of July 20, 1880.Another possibility is that he knew about theJacquard loom, since his brother-in-law and finan-cial backer was in the textile business. This de-vice, invented by a Frenchman, Joseph Marie Jac-quard, revolutionized the textile industry at thestart of the nineteenth century. It comprised a se-ries of cards with holes punched in them by whichweavers could pre-select warp threads to beraised or lowered, thereby creating intricate andrepeatable patterns. Simply, they could &dquo;pro-gram&dquo; the weaving process. Charles Babbage(1792-1871), considered by some the father ofmodern computing, also borrowed this notion ofthe Jacquard loom as the mechanism to inputquantities and instructions into his famous Ana-lytic Engine (Evans, 1981; Goldstine, 1972; at SAGE Publications on December 9, 2012ssc.sagepub.comDownloaded from 203Randell, 1975). In any event, the Hollerith Cardand Tabulating Machine caught on both in theUnited States and in Europe.The Hollerith System not only permanently af-fected the manner in which work was done; it alsoset the stage for some permanent changes in thenature of the work force. About thirty years earli-er Christopher Latham Sholes had invented thefirst workable writing machine. Initially, it wasused primarily by men for the &dquo;female mind hadbeen considered too flighty to master typing andthe female body too frail to operate heavymachines&dquo; (Austrian, 1982, pp. 70-71).
Entrepreneurial Setbacks
Hollerith: Inventor and Entrepreneur 11
Shortly before filing his first patent application in 1884, Hollerith
requested a loan from his sister's husband to finance the development
of experimental equipment. It was not the first time the
two men had considered joint business opportunities. Their previous
discussions had involved possible improvements in silk-weaving
equipment used in his brother-in-law's business.
Then came the
census of 1880. As that vast process went on, month after month, entirely
by hand, Billings at some point recalled a prototype device that might, with
adaptation, meet the needs of tabulating census results. In a conversation with
a young engineer, Herman Hollerith, Billings said ". . there ought to be
some mechanical way of doing this job, something on the principle of the
Jacquard loom, whereby holes in a card regulate the pattern to be
woven."
The Computer from Pascal to von Neumann, 1993, pp. 65-71 (7 pages)
While the returns of the Tenth (1880) Census were being tabu-
lated at Washington, Billings was walking with a companion
through the office in which h ~ ~ n d r e d sof clerks were engaged in
laboriously transferring items of information from the schedules
to the record sheets by the slow and heartbreaking method of
hand tallying. As they were watching the clerks he said to his
companion, "There ought to be some lnechanical way of doing
this job, something on the principle of the Jacquard loom, whereby
lloles in a card regulate the pattern to be woven." The seed fell
on good ground. His companion was a talented young engineer in
the office who first convinced himself that the idea was practicable
and then that Billings had no desire to claim or use it.3
One Sunday evening at Dr. Billings' tea table, he said to me
there ought to be a machine for doing the purely mechanical
work of tabulating population and similar statistics. We talked
the matter over and I remember. . . h e thought of using cards
with the description of the individual shown by notches punched
in the edge of the card. . . . After studying the problem I went
back to Dr. Billings and said that I thought I could work out a
solution for the problem and asked him if he would go in with
me. The Doctor said h e was not interested any further than to
see some solution of the problem worked
In reading over various speeches and papers by Billings on the
subject it seems to the author clear that Hollerith was the real
implementor of Billings' basic idea. Dr. Raymond Pearl, who was
for many years one of the world leaders in biology and biostatistics
and who was professor of biology and public hygiene at Johns
Hopkins, analyzed the situation in 1938 and concluded that "In
all essentials the case seems clear. Billings was the originator, the
discoverer, who contributed that which lies at the core of every
scientific discovery, namely, an original idea that proved in the trial
to be sound and good; Hollerith built a machine that implemented
the idea in practical performance, the accomplishment here, as
always of the successful inventor."
It is difficult to say more about the allocation of credit than Pearl
did. We will have occasion to see other examples of the difficulties
of allocating credit among men all of whom are deeply immersed
in a common project. Let us then agree with Pearl that Billings had
the basic idea and that Hollerith implemented it.
More importantly let us consider what the system was and what
use was made of it. Hollerith, proceeding on Billings' suggestions,
used a system of holes in a punch card to represent various charac-
teristics such as male or female, black or white, native or foreign-
born, age, etc. H e first designed his system using a continuous
roll of paper instead of individual cards. The card or roll of paper
then ran under a set of contact brushes which completed an elec-
trical circuit if and only if a hole was present. The completed
circuits activated counters which advanced one position for each

eing 19 years of age and a bachelor when he arrived in Washington to begin his new job, Hollerith became active in Georgetown social circles. He met Dr. John Shaw Billings at the Billings home one Sunday evening in 1880 through a supper invitation from Billings’ daughter. Although not trained as such, Billings was an cstablishcd expert in analyzing vital statistics, and the Census Bureau had appointed him Director of Vital Statistics for the 1880 census.2 That first encounter was the occlision for the famous but, ambiguously interpreted Billings-to-Hollerith transfer of the idea for a punched card machine to tabulate U. S. Census data. Interpreta- tions of Billings’ influence vary from “suggested the need for” to “suggested using cards with the description of the individual shown by notches in the edge of the card and a device something like a type distributing ma- chine.”
The material published in this sketch is extracted and edited from John Blodgett’s thesis presented in partial fulfillment of the Degree of Master of Science in Information Science at Drexel Insti-tute of Technology School of Lihrary Science, Phila., Pa., June, 1968. The original 234 pp. typescript is available on loan from the Drexel Library. Blodgett’s work began as a term paper and grew into a thesis because he gained access to hitherto withheld Hollerith family resourccs and was diligent enough to tap publicly available resources not previously consulted--to learn more of Hollerith’s personal story and to elucidate the controversial record of John Shaw Billing’s part in the development of the first punched card sorter.
