The stick-figure pictograms were popularized with their introduction by British Rail in the 1960s.
The gender symbol for female portable#
The modern symbols originate from use in the British Rail system, but are abstracted to varying degrees in different countries – for example, the circle-and-triangle variants (female) and (male) commonly found on portable toilets, to the extreme of a triangle △ (representing a dress) for female and an inverted triangle ▽ (representing broad shoulders) for male used in Lithuania. In public schools, the pictograms may be of children rather than of adults, with the girl distinguished by her hair. Since the 1960s, male and female pictograms – often color-coded blue and red – have become the norm for marking public toilets in much of the world, with the female symbol distinguished by a triangular skirt or dress, and in early years the male symbol stylized like a tuxedo.
Schoolhouse outhouses in the 19th-century United States had ventilation holes in their doors that were shaped like a starburst Sun ✴ or like a crescent Moon ☾, respectively, to indicate whether it was the boys' or the girls' toilet.
