The depiction of mathematics on stamps began in 1923 with the issue of a set of three Polish stamps commemorating the 450th birth anniversary of the astronomer and mathematician Nicolaus Copernicus. As the definition of what constitutes a valid mathematical stamp is not universally agreed, some collectors make the case that the first mathematical stamp was the 1847 United States issue depicting the polymath Benjamin Franklin even though he was not primarily a mathematician; [1] : 64 others prefer to recognize the 1926 German Leibniz stamp as the first depicting a mathematician. [2]
The total number of mathematical stamps that have been issued is approximately 1,600 as of 2024. [3] [4]
A mathematical stamp has one or more of the following characteristics:
Stamps illustrating applied mathematics such as astronomy, ballistics, cartography, crystallography, mathematical art, mathematical games, navigation, perspective in art and spaceflight may or may not be included in a mathematical stamp collection depending on the breadth of view of the collector. Typically such stamps may depict a mathematically related object or instrument, e.g. an astrolabe or a slide rule.
The following types of material are excluded (although they may also be collected by mathematical stamp enthusiasts):
Stamps depicting individual mathematicians are often issued by countries to commemorate the birth or death anniversaries of their significant national mathematicians, for example stamps issued by Norway celebrating Niels Henrik Abel. [8] [9] Examples are illustrated in the gallery above. Some countries have also issued stamps depicting internationally famous mathematicians such as Isaac Newton [10] or Albert Einstein. [11]
Stamps depicting a mathematical concept or object, sometimes combined with a portrait of the mathematician responsible for inventing the concept or object, are generally issued as commemorative stamps rather than definitive stamps. Examples are shown in the gallery above: a 1955 Greek stamp illustrating the Pythagorean theorem, a 1967 Brazilian stamp illustrating a Möbius strip and also commemorating the 6th Brazilian mathematical congress, a 1977 German stamp illustrating the complex plane and also commemorating the 200th birth anniversary of Carl Gauss, and a 1998 German stamp illustrating squaring a rectangle and also commemorating an International Mathematical Congress.
Stamps depicting a mathematical symbol or formula are frequently depicted together with the mathematician they are primarily associated with. Examples are shown in the gallery above: a 1966 Soviet stamp illustrating the integral, summation and union symbols and also commemorating an International Mathematical Congress, a 2000 Russian stamp illustrating the pi, [12] function and summation symbols and commemorating the life of Nikolai Luzin, a 2016 Czech stamp illustrating Fermat's Last Theorem and commemorating Andrew Wiles's 1995 proof, and a 2023 Serbian stamp illustrating the Fibonacci sequence and commemorating the 75th anniversary of Mathematical Society of Serbia.
Robin J. Wilson is the leading writer in the field having published a well-reviewed [13] [14] [15] book entitled Stamping through mathematics in 2001, [1] a paper on European mathematical history through stamps, [16] and also contributing the Stamp Corner column to The Mathematical Intelligencer starting in 1984. [3]
William L. Schaaf published a paper, [17] later expanded into a book entitled Mathematics and science: an adventure in postage stamps in 1978. [18] From 1979 until at least 2011 the Mathematical Study Unit of the American Topical Association published Philamat: A journal of mathematical philately but this organization is no longer part of the ATA as of 2024. A sample issue is available online. [19]
Listings of new issues of mathematical stamps are included in the monthly Scott Stamp magazine and in Linn's Stamp News; they are also available online from October 2010 to date in the Computers and Mathematics section. [20]
Philately is the study of postage stamps and postal history. It also refers to the collection and appreciation of stamps and other philatelic products. While closely associated with stamp collecting and the study of postage, it is possible to be a philatelist without owning any stamps. For instance, the stamps being studied may be very rare or reside only in museums.
Stamp collecting is the collecting of postage stamps and related objects. It is an area of philately, which is the study of stamps. It has been one of the world's most popular hobbies since the late nineteenth century with the rapid growth of the postal service, as a stream of new stamps was produced by countries that sought to advertise their distinctiveness through their stamps.
An overprint is an additional layer of text or graphics added to the face of a postage or revenue stamp, postal stationery, banknote or ticket after it has been printed. Post offices most often use overprints for internal administrative purposes such as accounting but they are also employed in public mail. Well-recognized varieties include commemorative overprints which are produced for their public appeal and command significant interest in the field of philately.
Indian postal systems for efficient military and governmental communications had developed long before the arrival of Europeans. When the Portuguese, Dutch, French, Danish and British conquered the Marathas who had already defeated the Mughals, their postal systems existed alongside those of many somewhat independent states. The British East India Company gradually annexed the other powers on the sub-continent and brought into existence a British administrative system over most of modern-day India, with a need to establish and maintain both official and commercial mail systems.
An airmail stamp is a postage stamp intended to pay either an airmail fee that is charged in addition to the surface rate, or the full airmail rate, for an item of mail to be transported by air.
In philately, a cachet is a printed or stamped design or inscription, other than a cancellation or pre-printed postage, on an envelope, postcard, or postal card to commemorate a postal or philatelic event. There are both official and private cachets. They commemorate everything from the first flight on a particular route, to the Super Bowl. Cachets are also frequently made, either by private companies or a government, for first day of issue stamp events or "second-day" stamp events. They are often present on event covers.
Topical or thematic stamp collecting is the collecting of postage stamps relating to a particular subject or concept. Topics can be almost anything, from stamps on stamps, birds, trains and poets on stamps, to famous physicians and scientists, along with historical people and events on stamps, which is often a standard theme for many stamp issuing countries.
The postal history of Malta began in the early modern period, when pre-adhesive mail was delivered to foreign destinations by privately owned ships for a fee. The earliest known letter from Malta, sent during the rule of the Order of St John, is dated 1532. The first formal postal service on the islands was established by the Order in 1708, with the post office being located at the Casa del Commun Tesoro in Valletta. The first postal markings on mail appeared later on in the 18th century.
The postage stamps and postal history of Armenia describes the history of postage stamps and postal systems in Armenia. Czarist Russian postmarks and stamps were in used in the territory of Armenia from 1858. The early postmarks were composed of dots in different shapes. Dated postmarks with city names soon followed. Many counterfeit postmarks are known. From 1909 until 1918 a few Russian stamps were overprinted identifying the Armenian Post. The Armenian letters H & P are intertwined, representing the initials of hai post, the Armenian Post Office.
The postage stamps and postal history of Israel is a survey of the postage stamps issued by the state of Israel, and its postal history, since independence was proclaimed on May 14, 1948. The first postage stamps were issued two days later on May 16, 1948. Pre-1948 postal history is discussed in postage stamps and postal history of Palestine.
The postal history of Turkey and its predecessor state, the Ottoman Empire, dates to the 18th century when foreign countries maintained courier services through their consular offices in the Empire. Although delayed in the development of its own postal service, in 1863 the Ottoman Empire became the second independent country in Asia to issue adhesive postage stamps, and in 1875, it became a founding member of the General Postal Union, soon to become the Universal Postal Union. The Ottoman Empire became the Republic of Turkey in 1923, and in the following years, its postal service became more modernized and efficient and its postage stamps expertly designed and manufactured.
Art Deco stamps are postage stamps designed in the Art Deco style, which was a popular international design style in the 1920s through the 1930s. The style is marked by the use of "geometric motifs, curvilinear forms, sharply defined outlines, often bold colors", and a fascination with machinery and modernity. This style strongly influenced contemporary architecture, furniture, industrial design, books and posters. Art Deco was named for after 1925 exhibit in Paris Exposition Internationale des Arts Décoratifs et Industriels Modernes. to which the American Topical Association has devoted a lengthy video. The exhibit lasted from April to October 1925 and displayed numerous objects in the new style. Examples of the style, however, are also found in the early twenties.
The postage stamps and postal history of Azerbaijan describes the history of postage stamps and postal systems in Azerbaijan, which closely follows the political history of Azerbaijan, from its incorporation to the Russian Empire in 1806, to its briefly obtained independence in 1918, which it lost to the Soviet Union in 1920 and re-acquired in 1991 after the dissolution of the Soviet Union.
The postal history of the Pitcairn Islands began with letters being sent without postage stamps, as none were available on Pitcairn. In 1921, the United Kingdom and New Zealand formally agreed upon a system to handle post from the island, but this arrangement was ended in 1926. In 1927, stamps from New Zealand were introduced. To improve the revenue generation of the colony, the British government established an official post office on the island in 1940. The opening of this post office saw the issuance of the first set of Pitcairn Islands stamps.

The Halfpenny Yellow is the first postage stamp issued by the Crown Colony of Malta. Depicting Queen Victoria, it was only valid for local postage and it was originally issued on 1 December 1860. It was the only stamp issued by Malta for two and a half decades, and during this period various reprints were made with differences in colour shade, perforation and watermark. When control of Malta's postal service was transferred to the island's colonial government on 1 January 1885, the stamp was withdrawn and it was replaced by a set of definitive stamps.
The depiction of chemistry on stamps began in 1923 with the issue of a set of definitive French stamps commemorating the chemist and microbiologist Louis Pasteur. Another early chemical stamp depicted the botanist and chemist Herman Boerhaave. The depiction of chemistry on stamps contributes to chemical education and to the public understanding of science.
The depiction of crystallography on stamps began in 1939 with the issue of a Danzig stamp commemorating Wilhelm Röntgen who discovered X-rays. Crystallographic stamps contribute to crystallography education and to the public understanding of science.
