The Symbol Group is a new International discussion group for symbol-related matters


We want to promote a deeper appreciation of the symbol in contemporary society, striving for more diversity and international understanding of the power of simple, direct communication.


We will generate biennial symposia using symbol anniversaries to promote the

understanding of symbols in contemporary practice.


Over the last decades, interest in symbols has grown with the rise of a growing global media culture. The primary objective of The Symbol Group is to critically re-evaluate symbol projects such as this to develop more effective visual communication for the future. 


The combination of our collective knowledge of historic and contemporary symbol culture provides this group with the perfect platform to realize this project and grow the network. Our founders are:

Symbol '22: Symbol Sourcebook @50

Virtual Symposium


The Symbol Group’s inaugural online symposium examined the 50th anniversary of industrial designer Henry Dreyfuss’ discipline-defining Symbol Sourcebook, to reveal the legacy underpinning our current fascination with emojis, icons and symbols and explore new symbol applications.


Industrial designer (March 2, 1904 – October 5, 1972)

Industrial designer Henry Dreyfuss (1904-1972) was one of the most successful American industrial
designers from the 1940-1960s, standing alongside other well-known industrial designers of the time such
as Raymond Loewy, Walter Dorwin Teague and Norman Bel Geddes.


His company Henry Dreyfuss Associates designed symbols for their clients from 1950-1965. Throughout his career, he was actively involved with individuals and organisations that wanted to develop and standardise symbols.


To highlighta few of his achievements as an industrial designer, Dreyfuss was responsible for the design of John Deeretractor Model A, (1939), The Round, (1953) and the Polaroid SX-70, (1972). As an author he wrote Designing for People (1955) and The Measure of Man (1960). Dreyfuss paid much attention to collecting data to promote usability and making this data publicly available. The universal tractor symbols he designed for John Deere and his work on distance symbols for the Polaroid Swinger camera show his
expertise in symbol design. He was also involved with clients trying to make symbols designed by Henry

Dreyfuss Associates into an American Standard. (See Russell Flinchum, The Man In The Brown Suit).

The Symbol Sourcebook was published in 1972 when the growth in internationalism fueled an increasing need for symbols to facilitate worldwide communication.

Symbol Sourcebook: An Authoritative Guide to International Graphic Symbols

by Henry Dreyfuss

This book is, as its subtitle suggests, ‘An Authoritative Guide to International Graphic Symbols’. It was
published in 1972 and has been reprinted many times. It contains an extensive collection of western
symbols. For a long time, it was the classic go-to-book for information on symbols. This may still be

the case. The Symbol Sourcebook is constructed using ‘discipline’, ‘subject’ and ‘form’ to categorize

the symbols.

2022 marked 50 years since Henry Dreyfuss first published his Symbol Sourcebook. The book forms a
comprehensive compendium of international symbols from both amateur and professional bodies.


The supporting archival material (a bequest of Dreyfuss before his death in 1972) is preserved by the Cooper Hewitt, Smithsonian Design Museum, New York, with whom we are collaborating to bring this project to fruition Dreyfuss’ Symbol Sourcebook represents a triumph of a collection, collation, design expertise, academic understanding, organisation, efficiency, administration, and editing. However, when the working papers and correspondence that went into its design and production are revealed, the book forms the tip of a massive graphic design iceberg which gives a unique window into the burgeoning discipline of graphic design in the late 1960s and early 1970s in relation to the creation of symbols for a world which was rapidly becoming consumed by internationalism.


The book also represents a graphic realization of the idealism which existed at that time for symbols to be the way forward for communicating in a world that was becoming more and more complex as internationalism took hold.

“If a system of symbols could be compiled that would be equally recognisable in Lagos and Lapland, perhaps the dream of a universal basic means of communication could be realised.

I believe this is possible.”
Henry Dreyfuss
