Nearly 40 examples of prints from three government survey expeditions to the American West: the U.S. and Mexico Boundary Survey, the U.S. Naval Astronomical Expedition to the Southern Hemisphere, and the U.S. Pacific Railroad Surveys.

From the mid-19th century, Americans have used simple instruments to assist them in doing arithmetic. Some of these did not actually add and subtract, but made it easier for users to do so. These included not only the abacus, but also devices called adders.

For most of human history arithmetic has been an act of human intelligence, aided only occasionally by devices like counters, the abacus, or the slide rule. The collections of the National Museum of American History document the development of adding machines, from stylus-operated models to increasingly compact, light and powerful key driven instruments. The corporate collections of the pioneering firms of Felt & Tarrant and Burroughs are especially well represented.

Advertising is meant to persuade, and the themes and techniques of that persuasion reveal a part of the nation's history.

Objects for math instruction reveal the changing role of arithmetic in American education. From the 1820s, teachers in public schools encouraged mental discipline by using textbooks and blackboards, while the teaching abacus and special geometric models utilized tactile learning. In the early 1900s, psychologists and math teachers used new educational theories to develop special flash cards, standardized tests, and educational games. During the 1950s and 1960s, more abstract approaches gained prominence. Recently, inexpensive electronic calculators have been used to teach— as well as perform —arithmetic.

The National Museum of American History is not an art museum. But works of art fill its collections and testify to the vital place of art in everyday American life.

The Art of Frank Gasparro consists of 115 drawings, plaster models, photographs, newspaper clippings and ephemera collected by, and related to, Frank Gasparro, the 10th United States Chief Engraver. Christina Hansen, Gasparro's daughter, donated the collection in 2009 to the National Numismatic Collection (NNC).

During World War I, the British blockade of German ports prevented American manufacturers from importing dyes for textiles, paper, and leather. See how one American silk company made a virtue of necessity by starting a fashion for dressing in black and white.

Beginning in the 14th century, a small number of European businesses kept careful written records of receipts and expenditures. These bookkeeping methods gradually diffused throughout Europe and the United States.  With the advent of typewriters and adding machines, many large retail firms, government offices, and banks invested in custom-made, expensive bookkeeping machines. The bookkeeping machines in the collection of the National Museum of American History come from a variety of makers, including adding machine manufacturer Burroughs, cash register maker NCR, and typewriter firms Remington and Underwood.

The Bristol-Myers Squibb European Apothecary is an eclectic collection of more than 1300 pharmaceutical artifacts assembled over a period of forty years by Dr. Jo Mayer, a German Jewish pharmacist.

This group contains the calculating machine collection from the Division of Medicine & Science at the National Museum of American History. During the late 19th and early 20th century, calculating machines served as common tools of scientists, engineers, statisticians, actuaries, government officials, and payroll clerks. Around 1970, calculating machines began to be replaced by cheap electronic calculators and the devices became hefty reminders of a bygone era.

These examples of original pen and ink comic art drawings were prepared for publication in newspapers across the country. The drawings date mostly from the 1940s, 1950s, and the 1960s. They help us look at American history through the reflective lens of the comic art medium. Their storylines and characters portray evil, ruthless, immoral, and corrupt individuals as well as their counterparts who assist a maintenance of American morals and a popular way of life.

The Comitia Americana series memorializes some of the pivotal moments of the American Revolutionary War. The series was created between 1776 and the early 19th century almost exclusively by French artists and artisans at the commission of the United States. The name of the series, Latin for American Congress, denotes that these medals were created after Continental Congressional votes to memorialize the heroism, friendship, and leadership of key American and French revolutionaries.  Each medal was struck either at the Paris Mint or the United States Mint in Philadelphia. The Smithsonian’s National Numismatic Collection currently holds 119 of these medals and 10 commemorative reproductions dating to the 20^th century. The iconography of each medal is deeply neoclassical in its use of heroic and Hellenistic portraiture, symmetrical panoramic battle scenes, and mythic scenes played as Revolutionary battles.

Tools of communication have transformed American society time and again over the past two centuries. The Museum has preserved many instruments of these changes, from printing presses to personal digital assistants.

Some of the simplest computing devices made and sold are aids to counting.  From ancient to early modern times, scribes performing calculations moved small stones or metal tokens along lines.  More recently, mechanical counters have been widely used to count crowds and objects,  and as parts of machines.

In the nineteenth century, several inventors patented mechanical counters.  Patent models surviving in the Mathematics Collections at the National Museum of American History suggest the range of their concerns. 

Furniture, cooking wares, clothing, works of art, and many other kinds of artifacts are part of what knit people into communities and cultures.

Dividers and compasses are instruments for mathematical and engineering drawings that have also been used in schools. Additionally, dividers were employed in conjunction with other measuring and calculating instruments, such as sectors. The metal, wood, and plastic objects in this collection were used in Europe, North America, and Japan from the 18th to the 20th centuries.

Washboards, armchairs, lamps, and pots and pans may not seem to be museum pieces. But they are invaluable evidence of how most people lived day to day, last week or three centuries ago.

While writing implements are found throughout NMAH, this object group focuses on about three dozen pens, pencils, and related objects in the mathematics collections. It illustrates some of the diversity in writing tools used for technical drawing in Europe and the United States from the 18th to the 20th centuries.

The expansion of American business, science, and technology in the years following World War II created a demand for powerful computing machines at a relatively moderate price. The development of compact electronic components—first sturdy vacuum tubes, and then transistors, made this a physical possibility; and led to the introduction of the desktop electronic calculator in the early 1960s.

In the course of the 1970s, handheld electronic calculators transformed the way tens of millions of people did arithmetic. Engineers abandoned slide rules, business people gave up desktop calculating machines, and shoppers replaced simple adding machines and adders.

A set of eight devices known as ellipsographs used to render ellipses in engineering and architectural drawings.

During the opening months of World War II, nearly 120,000 Japanese Americans, two-thirds of them citizens of the United States, were forced out of their homes and into incarceration camps established by the U.S. government. Many would spend the next three years living under armed guard, behind barbed wire. This collection explores this period when racial prejudice and fear upset the delicate balance between the rights of the citizen and the power of the state. It tells the story of Japanese Americans who suffered a great injustice at the hands of the government, and who have struggled ever since to ensure the rights of all citizens guaranteed by the U.S. Constitution.

The Smithsonian’s collection of kinematic models is housed in the National Museum of American History. These models were published by the German firm of Martin Schilling at the turn of the 20th century. Kinematic models were used to produce mathematical curves and other mathematical concepts useful to mathematicians, engineers and scientists.

The lace collection was started in 1908 to assemble a collection of arts and crafts for the Smithsonian Institution. From the initial 500 pieces it has grown to approximately 6,000 objects. Most of the objects originated in Europe and were donated by American collectors.

Almost 10,000 patent models reside in the Smithsonian’s collections—about 40 of them demonstrate marine inventions from the 1770s to the 1950s. These watery innovations offer a glimpse of the ways that inventors, particularly in the nineteenth century, sought to overcome the many challenges Americas encountered working and traveling on the water.

These objects illustrate the development of standard American weights and measures. The U.S. Constitution explicitly grants the federal government authority to establish uniform national standards. From 1834, these were customary British units. Not long after the French Revolution of 1789, France introduced a system of weights and measures that survives today as the metric system. These units were adopted internationally during 19th and 20th centuries. While the U.S. took steps to adopt the metric system, current American weights and measures remain a mix of the this system and customary units.

After the U.S. entered World War I in April 1917, the Army commissioned eight artists to record the activities of the American Expeditionary Force (AEF) in France. The mission of America's first official war artists was to capture the wide-ranging activities of American soldiers with the intent of shaping popular understanding of the war at home. Their collective output of more than 700 sketches, drawings, and paintings captured a rich and compelling “in-the-moment” view of the Great War. The Division of Armed Forces History holds over 500 pieces of this official artwork in their collections.

Situations frequently arise in which a person needs to measure the area of a two-dimensional space bounded by a closed curve. Planimeters are instruments used to help find that area, by tracing the curve with a needle point connected to a measuring wheel that converts the distance of the tracing to the result of an integral function. Planimeter users include cartographers representing landscapes with irregular boundaries, medical professionals measuring an image of a tumor or internal organ, biologists observing irregularly-shaped natural phenomena, or machinists monitoring steam engines for efficiency.

The Constitution made the presidency and the positions of senator and representative elective offices. By the early 19th century, rivalries among political factions in the new government led to the creation of a competitive party system. The promotion of candidates among an expanding electorate placed increasing importance on the success of popular political campaigns.

This collection of 23 objects illustrates the three main forms of sectors. They are made from brass, ivory, and wood, and they range in length from 3" to 13" when folded.

From the 18th through the 20th centuries, instrument makers and retailers sold a selection of dividers, compasses, protractors, curves and triangles, rulers, calipers, sectors, pencils, and other mathematical and drawing tools in sets to draftsmen, architects, builders, and engineers. These sets were often packaged in sturdy wooden cases or pocket holders covered in leather.

Slide rules were the primary calculating instruments for engineers, scientists, students, and others in North America, Europe, and East Asia from the late 19th century until inexpensive electronic calculators became available in the late 20th century. This collection of over 250 objects also illustrates earlier aspects of the history of slide rules and the variety of calculating tasks that inventors have attempted to simplify by designing slide rules.

The transportation collection in the Division of Work and Industry at the National Musuem of American History contains around 80 full-size automobiles. The automobile collection attempts to include significant automotive milestones as cars changed from horseless carriages to an intrinsic part of American life.

The nation's passion for sports is obvious every day—at NASCAR races, kiddie soccer matches, and countless other contests.

From the 17th through the 20th centuries, draftsmen, surveyors, navigators, military engineers, and architects used set squares, T-squares, L-squares, and drafting triangles to draw vertical, horizontal, and diagonal lines. These instruments were sometimes combined with scale rules and other drawing instruments.

Sushi, a Japanese food that comprises of cooked vinegared rice and ingredients such as fish, seafood, eggs, and vegetables, is a food type that has evolved over the centuries. What was once a delicacy for the nobles in Japan has been popularized to reach a wide domestic and international audience. Sushi, which traditionally comes in various forms, has taken on further adaptations to accommodate to local tastes.

Beginning in the late 19th century, Americans used special tabulating machines to compile the large quantities of data accumulated by governments, large businesses, and scientists. Operators punched holes in cards. Machines read these, accumulated totals, and sorted the cards for further processing. Tabulating machines would be displaced by electronic computers beginning in the 1950s, although punched cards remained in use somewhat longer.
