Commemorating Herman Hollerith: A Pioneering Force in Data Processing
Born on the 29th of February, 1860, in Buffalo, New York, Herman Hollerith’s 166th birthday is marked today. Esteemed as an engineer and inventor, Hollerith conceptualized a remarkably efficient punch card tabulator and founded a company that persists today under the name of IBM.
Hollerith exhibited an aptitude for engineering from a young age. At just fifteen, he enrolled in the Columbia School of Mines while spending his summer breaks laboring in the coal mines of Michigan.
Graduating in 1879 with a degree in mining engineering, he chose an unexpected path, taking up a position assisting Professor William Trowbridge in compiling a report for the U.S. Census on steam and power usage. With minimal responsibilities, Hollerith capitalized on his leisure time to indulge in Washington’s social scene.
The tale of how Hollerith engineered a punch card machine for automating the U.S. Census is indeed intriguing. His charm offensive was directed at Kate Sherman Billings, whose father oversaw a significant portion of the census related to vital statistics.
In a bid to impress Kate at a party, Hollerith endeavored to purchase all the lottery tickets available, yet fortune eluded him as he neglected just one—the winning ticket. When he opted for chicken salad at the buffet, it provided Kate the perfect opportunity to invite him to her home for a dinner featuring her mother’s renowned dish.
In the Billings household, an engaging discourse unfolded between Hollerith and Kate’s father regarding the challenges surrounding the census.
The elder Billings, convinced of the feasibility of a mechanical counting mechanism, sought Hollerith’s expertise, although he remained a physician rather than an engineer. Reflecting on their exchange, Hollerith recounted:
“He said to me that there ought to be a machine for doing the purely mechanical work of tabulating population statistics… He thought of using cards with the description of the individual shown by notches in the edge…
After studying the problem, I went back to Dr. Billings and said that I could work out a solution, and asked if he would go in with me. The Doctor said he was not interested any further than to see some solution worked out.”
Notably, Hollerith consistently credited Billings for the foundational concept of employing punch cards, humorously condensing his rationale for developing automatic data processing into the phrase “Chicken Salad.”
Initially, Hollerith’s punch cards featured perforations solely along the periphery as his punching apparatus could not access the center. However, it was not long before he rectified this limitation.
This innovation represented a reimagining of the punch card, a concept first introduced by Charles Babbage and adapted from the Jacquard loom.
Given that Hollerith’s brother operated within the silk industry, it is conceivable that he gleaned insights about card-controlled looms, though no direct evidence links him to Babbage’s work.
To validate the efficacy of his machines, Hollerith endeavored to streamline Baltimore’s disorganized health records. Demonstrating remarkable tenacity, he personally executed much of the card punching, managing 1,000 cards daily, each with upwards of ten holes.
Each card encapsulated data for a single patient; once punched, its tabulating and sorting mechanisms facilitated answers to inquiries that had previously appeared insurmountable.
His subsequent endeavor involved the automation of health records maintained by the War Department. Their willingness to rent his machines presented a more complex challenge, necessitating greater data storage per card.
Rather than merely enlarging the card size, Hollerith ingeniously devised combinations of holes to convey information, laying the groundwork for future coding systems that would ultimately evolve into binary and ASCII codes.
With his aspirations centered on securing a contract with the U.S. Census Office for the 1890 enumeration, Hollerith faced competition from two alternative approaches—one employing colored slips of paper, the other relying on poker chips.
In a trial utilizing data for 10,000 individuals, Hollerith’s machines accomplished the task in a mere three days, of which most time was dedicated to punching the cards; the actual processing took a mere five hours.
In contrast, the next fastest method consumed 4.5 days. Consequently, the Census Office ordered 56 machines, at an annual cost of $56,000, culminating in the completion of the 1890 census within one year, a stark contrast to the eight years required for the 1880 census.
In 1896, Hollerith established the Tabulating Machine Company to commercialize his census machines. By 1911, it merged with the International Time Recording Company and the Computing Scale Company to establish the Computing-Tabulating-Recording Company (CTR).
Just three years later, Thomas J. Watson Sr. took the helm as general manager, swiftly ascending to the presidency. In 1924, the company was rebranded as International Business Machines (IBM), heralding a new chapter in computing history.
Although Hollerith passed away in 1929, his punch card system remained in operation well into the late 20th century and beyond.
His legacy, though obscured for many modern programmers by the antiquated yet historically significant Hollerith constant in FORTRAN, exemplifies the indispensable role he played as a true pioneer in the realm of automated data processing.
