Crystallography on stamps

Stamps depicting individual crystallographers are sometimes issued by countries to commemorate the birth or death anniversaries of their significant national crystallographers,^[12] For example, on August 6, 1996, the British postal service (Royal Mail) issued a stamp honouring Dorothy Hodgkin, a pioneer of protein crystallography (Great Britain's first female Nobel laureate, in 1964, in Chemistry).^[13] Some countries have also issued stamps depicting internationally famous scientists associated with crystallography. For example, up to 2023, 55 stamps from 40 countries have been issued commemorating Wilhelm Röntgen the discoverer of X-rays.^[14][15]

A number of crystallographers have been awarded the Nobel Prize^[16] and have subsequently appeared on stamps.^[17] The following Nobel prize-winning crystallographers (or their work) have been depicted on stamps: Charles Glover Barkla, Paul D. Boyer, Lawrence Bragg, William Henry Bragg, Georges Charpak, Emmanuelle Charpentier, Francis Crick, Robert Curl, Clinton Davisson, Peter Debye, Johann Deisenhofer, Louis de Broglie, Jennifer Doudna, Ben Feringa, Andre Geim, Herbert A. Hauptman, Dorothy Hodgkin, Jerome Karle, Martin Karplus, Aaron Klug, Brian Kobilka, Harry Kroto, Robert Lefkowitz, Michael Levitt, Hartmut Michel, Konstantin Novoselov, Ardem Patapoutian, Linus Pauling, Max Perutz, Venki Ramakrishnan. Wilhelm Röntgen, Jean-Pierre Sauvage, Dan Shechtman, Richard Smalley, Thomas A. Steitz, Fraser Stoddart, George Paget Thomson, Max von Laue, Arieh Warshel, James Watson, Maurice Wilkins, Ada Yonath.

  Body-centred cubic structure, Belgium, 1958
• 
  Mining for minerals, Canada, 1963
• 
  Crystallogenesis, USSR, 1978

Stamps depicting a crystallographic concept or object are sometimes combined with a portrait of the crystallographer responsible for inventing the concept or object. Examples of crystallographic concepts and objects are shown in the gallery above: a 1958 Belgian stamp illustrating body-centred cubic structure, a 1963 Canadian stamp illustrating mining for minerals, and a 1978 Soviet stamp depicting crystallogenesis and commemorating Soviet-Polish cooperation in space flight.

  Geologist and garnets, USSR, 1968
• 
  Rhenium dimeric anion with a Re-Re bond, USSR, 1968
• 
  Amethyst, Romania, 2006

Stamps depicting crystals or crystallographic symbols are shown in the gallery above: a 1968 Soviet stamp depicting a geologist and garnet crystals, a 1968 Soviet stamp depicting a Rhenium dimeric anion with a quadruple Re-Re bond (Re₂Cl₈^2-),^[18][19] and a 2006 Romanian stamp illustrating amethyst crystals.

The International Year of Crystallography (IYCr) took place in 2014. To promote crystallography the following countries issued stamps to commemorate the IYCr: Austria (personalised), Belgium, India, Israel, Liechtenstein, Mexico, Moldova (personalised), North Korea, Poland, Portugal, South Korea, Slovakia, Slovenia and Switzerland.^{[7][20][21][22]}

No book has yet been published exclusively in the area of crystallographic stamps, however much crystallographic material is included in the book A philatelic ramble through chemistry by Edgar Heilbronner and Foil Miller.^[23]

Daniel Rabinovich is the current leading writer in the field having published articles on the International Year of Crystallography,^[7][8][22] and 35 articles covering chemistry, crystallography and physics philatelic subjects in the journal Chemistry International from 2007 to 2013.^[9]

The Chemistry and Physics on Stamps Study Unit (CPOSSU) of the American Topical Association has published a members' journal Philatelia Chimica et Physica since 1979 and a number of articles cover crystallographic topics.^[24]

Listings of new issues of crystallographic 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 Science & Technology section.^[25]
