The 1885 engraving of the Flapping Bird

  Information about the history of paperfolding found on the internet, and, indeed, in many older published sources, is often based more on myth and imagination than on fact and scholarship. The Public Paperfolding History Project aims to collect information from verifiable historical sources from which a more reliable narrative of the development of recreational paperfolding as a whole, and of individual paperfolding styles and designs, can be shaped, and to make this information publicly available for everyone to study and enjoy.

Objects made of paper are ephemeral and the record we have of them at an early date relies largely on their chance survival or their mention or appearance in poetry, books, fabrics, drawings, prints and paintings. It is likely that many practical and recreational paperfolds are much older than the earliest evidence we have for their existence. Unfortunately, of course, we cannot know, even approximately, how much older they might actually be.

It is my intention to record everything I can discover about paperfolding history up to and including 1970 in these pages. After that date designs and publications proliferate so fast that it would be impossible, for me at least, to record them all. I have recorded some information about later events, but only where the information is relevant to the development of themes that particularly interest me, such as the history of modular origami design.

The information I have recorded is drawn from texts in Japanese, Spanish, German, Dutch, French, English and several other languages. I am only fluent in English and rely on on-line translation tools for assistance. This will necessarily mean that I have made mistakes. If you find any errors or inaccuracies in these pages, or are aware of additional information, particularly early information, that I do not know of, or may have overlooked, please let me know.

Some of the information on this page comes from my own research. Much more of it, however, is drawn from the research of other people that has kindly been provided to me. I would particularly like to acknowledge the assistance of Juan Gimeno, Michel Grand, Masatsugu Tsutsumi, Edwin Corrie, Jaume Coll Guerrero, Koshiro Hatori, Joan Sallas, Laura Rosenberg and Coral Roma, but many other people have helped as well. It goes without saying that the late David Lister's writings on paperfolding history have also been invaluable (although they have not always proved to be accurate when the original sources have been located).

How to find information on this page
The first two sections below provide links to pages about Some Well-Known Designs and The Paperfolding of Some Well-Known People. Looking through a few of these may, I hope, encourage you to dig in a little deeper.

The following eight sections are made up of Topic Pages (which also function as indexes) gathering together material about various broad categories of designs and paperfolding techniques, although, in many cases material from the main sources and individual design pages has not yet been fully carried over. While this means that you cannot (yet) necessarily rely on them for a full historical narrative of the topic they cover, you can still use them to find out what designs in that particular category have a page of their own and to locate many designs which do not (yet) merit an individual page.

The next section is probably the one that you will want to use the most. It provides pages about Individual Designs, including all the best known 'traditional' designs (and some that you may never have heard of before). Designs tend to have different names in different books, at different times and, of course, in different languages. To simplify this situation I have given each of the designs that have an Individual Design Page a standard name. Usually this name is in English, but sometimes it is in another language. These standard names are used in the headings in the Index Pages and in the main body of the Source Pages (see below), where they appear in bold. This should, hopefully, help you find the Individual Design Page for the design you are looking for. If you cannot find a classic or 'traditional' design in these pages please feel free to contact me.

If you want information about, for instance, the history of paper planes in general, you can find this in the Index Pages - Inanimate Objects section. If you want to look up the history of one particularly paper plane, say the Paper Dart or the Swallow, you can find this in the section about Individual Designs.

Individual Designs generally only have their own pages if they occur several times in the literature. Details of designs that only appear once or twice may not have their own page but information about them will appear in the Index Pages.

In most cases I have not made individual pages for designs that can be attributed to a specific designer, but you can still often locate where these designs are published by looking at the page about the work of the specific designer or the type of origami involved eg modular.

Finally, right at the foot of this page, there is a section about Sources, which provides information about many of the historical documents on which the other pages are based, and, in many cases, provides a link to a full online version of the document the information is drawn from. If you know of any other significant sources of information that I have overlooked please let me know.

Where sources are shown but are not yet linked to pages it means I have information on what they contain but have not yet found time to add the information here.

Where Sources Pages are marked 'incomplete information' it means I have not yet been able to obtain a full print copy or find a full electronic copy on line. If you can make up for these deficiences I will be extremely grateful.

Where Source Pages are marked 'not yet fully integrated' it means I have not yet fully carried the information they contain over to the Index and Individual Design pages.

Where Index or Individual Design pages.pages are marked 'incomplete' it means that I have information that has not yet been added to these pages, in some cases a great deal of information.

All pages are subject to updating as new information becomes available.
