This podcast talks about how some of the most ubiquitous icons came to exist, and I found the history of the peace symbol particularly interesting. It was designed in 1958 as a logo for a protest march against nuclear war in London. The lines in the symbol actually mean ’N’ and ‘D’––which stand for nuclear disarmament––in semaphore. (Semaphore is a way to communicate messages at a distance using flags). This is an example relevant to our discussion about icons, symbols, and indices, and how they can effectively and concisely bring something to mind for the viewer (peace, in this case).
