The U.S. Postal Service can trace back its roots to before the American Revolution. From the early 18th century, the British government handled colonial mail delivery, which was limited to a few locations in towns and cities along the Eastern seaboard. An early employee of this colonial service was Benjamin Franklin, who became postmaster of Philadelphia in 1737, when he was just 31 years old, and then co-postmaster general for all 13 colonies a few years later. During this time, Franklin improved service, extended existing delivery routes and introduced new ones. He also ran afoul of his bosses. A leading figure in the independence movement, he was fired in 1774. He wasn’t out of work for long, though. Just weeks after the Battles of Lexington and Concord, Franklin was put in charge of the newly formed United States Post Office in July 1775, earning $1,000 a year as the first U.S. postmaster general. One of Franklin’s most lasting legacies was the establishment of the Inspection Service, America’s oldest federal law enforcement agency. Established to prevent fraud and misuse, it has grown from just a few agents to a present-day workforce of more than 7,000 agents, clerks, investigators and armed personnel. Over the past 200 years, the Inspection Service has tackled a wide variety of issues, from mail fraud and theft to enforcement of the 1873 Comstock Law prohibiting the distribution of “obscene” materials through the mail, such as in the case of the post-9/11 anthrax scare. Post-Revolution, the job of delivering America’s mail was considered so important that the U.S. Postal Service was written into the U.S. Constitution. In fact, for more than 150 years the postmaster general was a cabinet-level position, and the office-holder was even in the line of presidential succession, albeit in last place.
In an effort to handle the increasing amount of mail it processed and delivered, the Postal Service became an early adopter of transportation technologies. While delivery on foot and on horseback was the norm during its early years, they also arranged for contracts with stagecoach and steamboat operators that allowed them to speed up delivery times and keep pace with the country’s westward expansion. They quickly realized the impact the railroad would have on American life. Less than a decade after the introduction of the steam locomotive in America, Congress had declared every railroad line in the country an official postal route, and upon the completion of the first transcontinental railroad in 1869, the Railway Mail service began operations. These mobile mail movers’ sole purpose was to pick up, sort and deliver vast amounts of correspondence. At its height in 1930, Railway Mail was operating more than 100,000 trains before finally ceasing operations in the 1970s. The Postal Service also began experimenting with automobile delivery around the same time, and by 1911 seven different cities were being serviced by newfangled “motor wagons.” And while the rest of the U.S. government remained skeptical of the possibilities provided by air travel, the Postal Service had no such doubts. Initially, the U.S. Army handled delivery airmail, but when they proved reluctant to increase transport numbers, the Postal Service assumed control of operations in 1912. They hired a full staff of civilian pilots, whose salaries could reach today’s equivalent of $65,000, and began regularly scheduled service between cities on the East Coast. Today, more than two centuries after its first employees hit the road, the Postal Service maintains a fleet of over 260,000 vehicles, the largest in the world. While they embraced some new technology, the Postal Service clung to a few outdated methods for far longer: Parcel-sorting machines of any kind weren’t installed until the 1950s, and zip codes weren’t introduced until the 1960s.
