Before the filing cabinet, every document in an office had to be folded.
In 1898, Edwin Grenville Seibels, a clerk in his father's insurance firm in Columbia, South Carolina, realized that the standard method of storing documents was wasteful. Papers were folded into envelopes and placed in arrays of pigeonholes lining the office wall. Finding a document meant searching through envelopes, opening each one, and unfolding the paper inside.1
Seibels recognized that folding was unnecessary. Papers could stand on their edges, upright in drawers, organized by dividers. He presented specifications for his vertical filing system to the Globe-Wernicke Company of Cincinnati, which built five wooden filing boxes to his design.
Seibels applied for a patent, but the application was denied on the grounds that his filing system was an idea, not a device.2 He received a bronze plaque in recognition of the invention instead. The vertical filing cabinet went on to become the dominant method of document storage in offices worldwide for most of the twentieth century.
Before Seibels, Henry Brown, an American inventor, had patented a horizontal filing cabinet in 1886. Flat-file systems and pigeonhole cabinets had been used in offices for decades. What Seibels introduced was the vertical principle: documents standing upright, accessible from the front, in deep drawers that could be stacked.3
The filing cabinet shaped the physical architecture of office work for a century. By the 1950s, a large corporation might maintain entire floors of filing cabinets staffed by filing clerks whose sole job was to store and retrieve documents. The digitization of records, accelerating from the 1980s onward, made the filing cabinet increasingly obsolete, though millions remain in use worldwide.
